The Incredible Shrinking Buffalo

The Incredible Shrinking Buffalo

Ancient Bison in North Dakota include Bison latifrons, a giant buffalo with long and only-slightly curved horns now extinct, at left, and decreasing-size species that once lived in the western US. Only the smallest of them all—the Bison bison, at right, survives today. They exist in two subspecies: Bison bison bison of the plains and Bison bison athabascae of the far north.

The small party of Native American hunters were excited when they discovered a herd of bison grazing on open high prairie near some large hills connected by a steep ridge.

The experienced and opportunistic hunters quickly noted that the terrain favored them. Several arroyos, perhaps 30 feet deep and a hundred feet wide at their mouths, cut into the crumbly red sedimentary siltstone that formed the base of one hill.

These erosion features looked like possible escape routes to the bison, but their channels narrowed quickly so that they essentially became small box canyons.

The hunters recognized that, if they were to drive their prey into the gullies, the walls would be too steep for the bison to climb and the animals would have no room to maneuver.

The hunters could then get close enough to the large beasts and dispatch them with atlatl darts while standing safely on the rim of the arroyo.

The Indians executed their plan, killed a number of bison and butchered them where they lay.

The bones and projectile points were soon covered by mud and remained there for six thousand years until a cowboy discovered some of them protruding from the walls of the arroyo.

The find was reported and was subsequently excavated by famed archaeologist George Frison and his crew from the University of Wyoming.

The find was named the Hawken Site after the owner of the ranch on which it was located, about 25 miles west-southwest of the Vore Buffalo Jump.

It proved to be one of the most important sites for the period it represented, the so-called Mid-Holocene Warm Period (a.k.a. “altithermal”).

The buffalo killed were of a species named Bison occidentalis that would become extinct fairly soon after the Hawken hunt.

B. occidentalis was one of several bison species that died out, leaving only Bison bison, often called buffalo, in North America.

The Bison Family Tree

Bison latifrons—An extinct giant buffalo.

The ancestors of modern bison appeared in Asia about two million years ago. They roamed the “steppe,” a vast, flat, grassland that stretched across southeastern Europe and much of Siberia at the same time as the progenitors of mammoths.

Steppe Bison—Ancestor of all North American bison species.

The modern buffalo are descendants of an older, larger species called “Steppe Bison” with the Latin name Bison priscus.

Steppe Bison shared the Old World with several other bovine species, including the Aurochs Steppe Bison—Ancestor of all North American bison species that gave rise to modern domestic cattle and several species of Asian and European bison.

During the last Ice Age, so much of earth’s water was tied up in glaciers that sea level was almost 300 feet lower than it is now.

Many continental shelf areas currently covered by shallow saltwater were exposed and became land between 240,000 and 220,00 years ago.

One such region was the seafloor between Siberia and the Seward Peninsula of modern Alaska. Falling sea levels there resulted in a land bridge that connected Asia with North America.

Animals were able to move both directions over this neck of land. Among other species, bison, mammoths, wolves and, later, humans and their dogs found their way into the Western Hemisphere.

Horses and camels moved the opposite direction, evolving in the New World but finding new homes in Eurasia. Horses evolved in North America but died out here after they crossed the land bridge and established themselves on the Eurasian steppe.

Horses were eventually domesticated and returned to their birth-continent with the Spanish Conquistadors in the early 1500’s.

The bison family tree branched after it was established in North America. The Steppe Bison is thought to be the ancestor of three now-extinct bison species, and eventually, the modern buffalo. The extinct species were all larger than the today’s bison.

The largest individuals of B. latifrons had a shoulder height of 8.2 feet and weighed as much as 4,400 pounds (25% to 50% larger than biggest modern buffalo). Some individuals possessed relatively straight horns more than three times longer from tip to tip than today’s bison.

B. latifrons lived in the warmer middle of North America grazing the grasslands and browsing in the forest. It became extinct between 21,000 and 30,000 years ago

Bison antiquus — One of the “megafauna”

A second species, Bison antiquus, is thought to have evolved from B. latifrons.

B. antiquus was still massive (7 ½ feet and 3,500 pounds) with a more pronounced hump and less bulky hind quarters. Its curved horns also measured 3 feet from tip to tip.

They also lived in the midcontinent but were extinct by about 10,000 years ago along with many other species of the so-called megafauna (including saber-tooth cats, dire wolves, short-faced bears, mammoths and giant sloths).

There is much conjecture about the possible role of human hunting in these extinctions. Most likely these species were already stressed and declining because of changes in climate and ecology, but hunting by Native American was probably a factor in the extinctions.

The Hudson Meng Site managed by the US Forest Service on the south end of the Black Hills (20 miles northwest of Crawford, Nebraska) is an excellent place to see B. antiquus bones.

It is a large kill site apparently the work of Indians of the Alberta and Eden cultural complex.

A poster of a Bison occidentalis skull from the Hawken Site imposed over a photo of the Wyoming arroyo where it was killed 6,000 years ago.

The third species, Bison occidentalis, was the species found at the Hawken Site. It was descended from B. antiquus and was intermediate in size (6 feet tall and 2,200 pounds) between this ancient species and modern bison.

B. occidentalis became extinct near the end of Mid Holocene Warm Period about 5,000 years ago, but not before it gave rise to the modern Bison bison (6 feet tall and 2,000 pounds).

The abnormally warm period lasted from about 7,000 to 5,000 years ago and is thought to have been caused by slow and minute changes in the earth’s orbit.

During this time, the Northern Hemisphere was both warmer in summer and colder in winter than at present.

The result was that the Great Plains were drier and produced less forage for grazing animals like bison than it does now.

Lower elevation regions shifted toward desert-like conditions during the Mid-Holocene.

Populations of both prey animals and humans fell. Animals were attracted to higher elevation ranges such as the Black Hills and Bighorn Mountains, which were cooler with more precipitation.

There are fewer archaeological sites from the period, and most of them have been found at higher elevations.

That may explain why the B. occidentalis killed at the Hawken Site and the B. antiquss at Hudson-Meng were near the well-watered Black Hills.

(Another buffalo jump was partially excavated last summer on a ranch a few miles east of the Vore Site. The bison skulls found there appear to be B. occidentalis, though definitive carbon dates on the specimens are still pending.)

In any case, the more extreme conditions were probably a factor in the extinction of B. antiquss and B. occidentalis, and their replacement by the two subspecies of buffalo we know today.

The extant subspecies are the familiar Plains Buffalo (Bison bison subspecies bison) and the somewhat larger Wood Buffalo (Bison bison subspecies athabascae).

The latter live in or near the boreal forest in Canada. There are some differences in body form, behavior, habitat and forage preferences between them.

Their current ranges are separated by considerable distances. However, the subspecies can crossbreed and produce viable offspring.

In fact, in the desperate days when modern bison were hanging by a thread over the abyss of extinction, bison from the Plains [may have been] interbred with somewhat larger Mountain Buffalo that hung on in Yellowstone.

All of the buffalo killed at the Vore Site were Plains Buffalo, and the period in which the Vore Site hunts occurred was a colder, wetter time called the Little Ice Age.

Nature is dynamic. Change is constant. Living things must adapt or become extinct.

As the post-glacial period brought drier conditions to their primary habitat, bison adapted genetically by reducing their body size and, thus, their forage requirement.

Anyone who has spent time observing buffalo at close range is likely to be impressed by their size, power, speed, agility and general toughness. They are large, often unpredictable and potentially dangerous wild animals.

Modern bison are smaller than their extinct predecessors, but their population increased dramatically after the Holocene Warm Period.

Before the intentional destruction of the great herds in the 1800’s, there were, conservatively, thirty to forty million buffalo on the Great Plains.

In that environment, buffalo were so well adapted and abundant that the Native Americans of the region built their entire cultures around the great beasts.

For the “Last Great” hunt here at Hiddenwood, 2,000 men, women and children traveled here from Ft. Yates on about June 20, 1882. Quietly the hunters rode up HIddenwood Creek (from the far left) spread out onto the hills on all sides, where as Agent James McLaughlin’s wrote, “50,000 buffalo” were grazing. They killed 2,000 buffalo the first day. The 2nd day they quick-butchered and cared for the meat and on the 3rd day they hunted again since the buffalo had not moved far, killing 3,000 more.

Then they camped for a time to dry and preserve the meat. Everyone knew their tasks: the men cut apart the large bones and hauled the meat into camp, while women cut it into thin sheets and hung them on willow branch frames and stretched and pegged hides to the ground to dry in the sun.

Young people enjoy the authentic tipi set up at the Hiddenwood Historic Site on the highway—also known as the Yellowstone Trail in this area. This tipi framework represents the many stone circles that filled this broad valley when first settlers arrived and the thousands of years before that when various Plains tribes came to hunt buffalo here and camped near the cliff which they called Hiddenwood. So named because it could not be seen until just before they came over the nearest hills. (The canvas tipi coverings made and set up by skilled Lakota craftsmen have been vandalized twice, so instead the poles are now anchored in place to suggest the proper tipi framework.) Photo KBW.

 

 

Once called the Butchering Site because of the abundance of buffalo skulls and bones found here when settlers arrived—we now call this the “Sitting Bull Hunt Site.”

Sitting Bull and his band came from their agency west of Mobridge—either to this place or within a few miles and killed the very last great herds of buffalo—about 1,200—on October 12 and 13, 1883. This was the Last Stand of the great herds of wild Buffalo.

William Hornaday, head taxidermist at the Smithsonian Museum, who wrote “The Extermination of the American Bison” in 1887 and predicted the buffalo would soon be extinct wrote “There was not a hoof left!” His book was published in 1889 by the US Government Printing Office.

The BSC visitors were encouraged to visualize significant events that took place here in this “most beautiful valley in our area,” where the land which looks much as it did 150 years ago:

In the centuries before they owned horses and guns, ancient Native Americans hunted here with homemade weapons and cared for their meat. Women dried buffalo meat on willow racks and stretched their hides.

in 1823 Major Henry came up the North Grand River with his fur trading party, although one of his tough mountain men, Hugh Glass, was severely injured by a grizzly bear and left to die near Shadehill without his weapons.

General Custer rode through here with 1,200 men of the 7th cavalry, 200 covered wagons pulled by 6 mules each, a medical team, gold miners, reporters of leading newspapers, Native American scouts, his 7th Cavalry band—in the mornings dispatched to play military airs including Custer’s favorite (“The Girl I left Behind”) from a nearby butte as the Calvary rode by with flags flying. In addition, 300 head of beef cattle were driven along by cowboys to be butchered and fed as needed to the two thousand men on the expedition to the Black Hills in 1874.

And finally in this place we can imagine “Ghost riders in the Sky.” Texas cowboys trailed great herds of longhorn steers, a thousand at a time, from over the far horizon. The steers fattened and grew larger as they grazed our high-protein grasses. Some said so did horses and even the cowboys when they came up north! Photo Credit Kendra Rosencrans.

The archeological record indicates the hunters butchered some of the animals on-site, preparing and packing a portion of meat for transport, breaking open log bones with cobble to extract marrow, and re-tooling for the next kill.” Photo JK.

Five Tips to Keeping Livestock Vaccines Viable on Farm

Vaccines are crucial to keeping livestock healthy and productive, says South Dakota State University (SDSU) Extension Veterinarian and State Public Health Veterinarian Russ Daly.

While vaccines don’t provide absolute protection, the “added insurance” helps stimulate the animal’s immune system and increases its ability to fight off an infection or lessen the impact of disease if it should occur.

“Herd history, vaccine type, method of administration and age of animal all come into play, so it is critical for producers to work with their local veterinarian in developing a vaccination program,” says Daly. “They have experience with and knowledge of the many different vaccines, as well as the disease issues in area herds.”

Most vaccines are either modified-live virus (MLV) or inactivated “killed.” MLV vaccines contain whole germs that have been altered such that, while they are able to multiply within the body, their ability to cause disease has been taken away. Inactivated vaccines contain bacteria or viruses that have been inactivated by heat or chemicals.

Whether the producer/veterinarian team chooses an inactivated or MLV vaccination program, Daly says it’s important that the vaccines don’t go past their prime.

“Proteins are the major components of the organisms that make up both killed and MLV vaccines, and they disintegrate according to two major factors: time and temperature.

In addition, common disinfectants and ultraviolent light can reduce the viability of modified-live organisms.

Daly recommends the following tips for handling, storing and using vaccines:

  1. Purchasing vaccines and equipment: Observe expiration dates prior to purchase. Purchase the appropriate type and sufficient number of needles for the job. Plan on replacing needles when they become bent, dull or dirty, and before drawing up vaccine into the syringe.
  2. Transporting and storing vaccines: Keep boxes and bottles cool and out of sunlight while in transport. Use frozen ice packs in an insulated box in the summer and prevent vaccines from freezing in the winter. Prior to use, store vaccines in a properly working refrigerator.
  3. Equipment and work area: Use clean syringes, but not those that have had internal parts cleaned with soap or chemical disinfectants, including alcohol. Set up an area for syringes such that they are shaded and kept cool and dust-free while working.
  4. While working: Keep vaccine bottles in a closed cooler with ice packs (summer) or hot packs (winter) until they are needed. When using MLV vaccines, rehydrate the vials either one at a time as they are needed or as many as you will use within an hour. Always use a brand-new needle to draw vaccine into the syringe. Protect syringes from heat, light and freezing while working. When using needle-free injection systems, or syringes that draw doses from a tube attached to the vaccine bottle, care should be taken to assure the bottle and tubing stay cool and shaded from sunlight.
  5. After job is complete: Discard any unused MLV vaccine that has been reconstituted. Discard any partial bottles of inactivated vaccine that have been contaminated by dirty needles. Return unmixed MLV and unused inactivated vaccines to a properly working refrigerator as soon as possible. Clean syringes, transfer needles and tubing. Follow the manufacturer’s directions on proper cleaning and maintenance of needle-free injection systems.

Day 1—Friday, June 23, 2022

On Day 1 we learn about the changing role of the bison from Pleistocene time until the present, as well as its cultural significance to our Native citizens.

President of Bismarck State College Dr. Douglas J. Jensen welcomes participants to the Bison Symposium that finally became a reality after nearly three years of planning. Who knew when we began to talk about the importance of our national mammal—the bison or buffalo— their near extinction and the conservation efforts involved in the restoration to Native and federal lands, that travel restrictions caused by a worldwide pandemic would postpone or even threaten cancellation of the symposium? Co-chairs of the BSC Bison Symposium committee are Dr. Larry Skogen, President Emeritus of BSC, and Erik Holland, Curator of Education with the State Historical Society. The BSC Dakota Bison Symposium, was made possible by the generosity of the National Endowment for the Arts, Rockstad Foundation, and Bismarck State College Foundation. All persevered and we are delighted to have overcome all obstacles. Photo credit James Kambeitz.

Here Andrew C. Isenberg, Distinguished Professor of American History at the University of Kansas and author of ‘The Destruction of the Bison,’ explains how millions of bison were slaughtered to market the hides, meat, tongues and bones. “Like other environmental catastrophes in the American West . . . the destruction of the bison was in part, the result of the unstainable exploitation of natural resources,” he said.

A panel discussion of the restoration of bison and economic aspects of raising buffalo included Kevin Leier, at left, executive director of the North Dakota Bison Association, Brendan Moynahan, Chair of the Department of Interior’s Bison Working Group and planning for the National Park Service, and Arnell D. Abold, who served 4 years as Executive Director of the InterTribal Buffalo Council, is a member of the Oglala Lakota (Sioux) tribe, and now works with the Tanka Fund to help restore bison to tribal lands.

 Abold devotes her career to the vision of seeing Bufalo on the land, believing “that Buffalo are the connection for our people to believe in a better tomorrow and together we can help create a reality that empowers us to live not only a better today but inspires us to keep fighting for a better future for the people, the land and the Buffalo.” Photo Credit JK.

Shadehill Buffalo Jump from the north side of the lake. When first settlers arrived in the area, 2 layers of buffalo bones were exposed across the face of this steep cliff for about 100 ft up and down the river, according to SD author Archer Gilfillan. The first layer, 12 feet deep was about 25 feet below the top of the cliff. Beneath that was a 4 ft layer of earth, then a 2nd layer of bones 4 ft thick—the bottom of which was 100 ft above the bed of the river (before the dam was built in the 1950s).

The bones of the jump—like most known buffalo jumps in the US and Canada were “mined” and the bones shipped to munitions plants on the west coast during WWII. Phosphorus was extracted for explosives. This was one way people at home supported the war effort.

Buffalo jumps have 3 parts: the bone pile below, a steep cliff, and most important of all, drive lines on the plateau above where buffalo often graze. Native leaders who made the buffalo jumps work had a deep understanding of buffalo behavior. Religious rites, traditional dancing and prayers also played an integral part in the hunts. These were people without horses or guns. They prayed for courage, skill and teamwork, as well as cooperation from their relatives, the buffalo. Photo KBW.

This view from the south side of Shadehill Lake leads out to the buffalo jump cliff itself. “I’ve tried to sketch here what might have happened. The best kept secrets of success are not with the drive lines themselves, brush and branches waving from both sides—although these were necessarily carefully engineered to keep the wild herd on track,” according to author FM Berg. “Dr Jack Brink, Canadian anthropologist and author of the book ‘Imagining Head-Smashed-In’ says he never read about this next technique in any book, but was told by a Blackfeet elder that before the buffalo were brought up, a trail was made down the center—by a hunter who pulled a buffalo hide behind him dropping buffalo chips all the way, while covering his moccasin tracks.

“Then he adds that some tantalizing activity is used to tempt the herd to charge down the trail. A medicine man might prance and dance calling and singing to the buffalo, exciting and attracting their curiosity.

“Or even better, a couple of young men scuffle on the trail, one wearing a wolf skin and the other a buffalo hide. The pretend calf bleats out with a perfect imitation of desperate calls for help—and anxious mothers in the herd come on the run to rescue him from the snarling pretend wolf. By this time the herd is in frantic stampede—and off the cliff they go.

“However, it’s a very dangerous place for everyone at the cliff drop-off waving hides, trying to prevent buffalo from escaping off to the side. If one gets past, the others might follow and all is lost.” Photo FMB.

Buffalo Roam Free at the 7,000-Acre Battelle Darby Creek Metro Park In Ohio

Did you know that there’s a place in Ohio where the buffalo roam free? Few people do.

Battelle Darby Creek Metro Park in Galloway, Ohio is home to two prairies where you can watch these majestic animals graze.

It’s a hidden gem beloved by locals and a pleasant surprise to visitors who aren’t from the area. Here’s why this truly unique park is a must-visit, no matter what time of year it is:

Stretching across more than 7,000 acres, Battelle Darby Creek Metro Park is home to a herd of bison that roam free. It’s a best kept Ohio secret.

The buffalo roam freely within two enclosed pastures. You can often view the herd from the Darby Creek Greenway Trail, the bison overlook deck and the Nature Center.

Once the spring season hits, the bison get a health check-up before they’re released from the winter grazing area and sent into the prairie pasture.

In addition to watching these majestic creatures roam, you’ll want to check out the wetlands—a diverse landscape makes this park special.

Vore Buffalo Jump—Part 2

The Vore Jump site is considered important because of its location and the period of time it was used for buffalo hunting.

Literally it is located a stone’s throw from a major highway—I-90—the longest transcontinental freeway and interstate highway in the US which crosses the US from Boston to Seattle (3,021 miles; 4,862 km).

This northernmost transcontinental route was established in 1956, so it sees lots of traffic, especially in summer with families traveling to mountain vacation lands.

In fact, it made a rare curve to avoid the Vore Buffalo Jump itself—which was discovered by highway engineers surveying the I-90 route.

Because it is on a major route, people on the Vore Foundation board point out that their Buffalo Jump is the most accessible of the major Plains Indian sites to the traveling public.

“Thus it provides a perfect physical context for illuminating Plains Indian culture and history and presenting it to visitors.”

The importance of the Vore Jump is that it marks a clear transition in major movements of Native Indian populations from east to farther west after European settlement began on the east coast.

It was used as a buffalo jump for about 250 to 300 years, beginning in around 1500 when Europeans were just beginning their encroachment of lands on the Atlantic Seaboard.

Map shows where I-90 goes west from Spearfish SD in the Black Hills, takes a swerve at the Vore Buffalo Jump site, from which it’s only a few miles to Devils Tower National Monument and on beyond to the east entrance of Yellowstone Park via Beartooth Pass and Cooke City.

At that time, all Native weapons and implements were hand-made of bone or rock, sometimes traded from one tribe to the next. Dogs pulling travois were used to haul their goods.

Then came a time of western movement of Indian tribes. Many tribes left their homes and adopted a nomadic Plains lifestyle that followed buffalo herds, embracing a new culture interrelated with and dependent on the buffalo for most all their needs.

For most of their history, meat and hides obtained from buffalo jumps were used by Native Americans for their own subsistence. But as manufactured items became available, Plains tribes began trading for them with tanned buffalo robes, jerky and pemmican.

Gradually metal tools and guns became trade items that occasionally reached the Plains tribes, and they learned to value trade goods from various sources—beads, cloth, blankets, guns, knives and unfortunately, alcohol.

Then during the early 1700s some tribes, beginning with the Comanche and Apache in the south, began trading for horses that escaped the Spaniards—who had tried mightily to prevent Natives at Mexican border missions from learning to ride.

By 1750 horses reached the northern tribes, led by the Shoshone, who raised great herds of horses at an early date.

Native tribes understood the advantages of the horse immediately. They grew up from childhood with horses, trained them, rode long distances in war, raiding and hunting. They became some of the greatest horsemen the world has ever known.

And since on horseback, hunters could surround a herd of buffalo, ride alongside and kill their target with one bullet to a fatal spot—usefulness of the Vore Buffalo Jump came to an end about 1800. It had outlived its purpose.

Eventually horses made buffalo jumps obsolete, but trade expanded. Archaeology at the Vore Site will help us understand when and how this transition occurred.

We might say that the Vore Buffalo Jump Foundation is notable further because it is a non-profit organization in the finest sense. More about that later.

Interstate highway I-90 swung to the left in this photo to avoid the historic Buffalo Jump at the Sinkhole. It gets a great deal of east-west travel and is considered a major route to summer vacation lands in the mountains. VBJF.


When they were told they had to erect a handrail or close, the foundation had pretty much spent its last dime and requested donations. Local people who supported the project stepped up. Even a touring 4th grade class opened their pockets and donated—and the railing went up quickly. VBJF.

Who used the Sinkhole Jump?

Buffalo bones are found at 22 levels at the Vore site, the top levels are most recent from about 1800. VBJF.

While no specific level of the sinkhole has been designated to one cultural group, the tribes who most likely used the Vore sink hole were the Lakota Sioux, Cheyenne, Arapaho, Crow, Kowa, Plains Apache and Shoshone, according to Greg Pierce, PhD, a Wyoming Archeologist who earned his graduate degree at the Vore Buffalo Jump site.

Dr Pierce’s specialty was weapons and implements used for butchering the bison trapped in the sinkhole at Vore. Pierce also served on the Vore Foundation Board for 12 years

Working with only the 6 upper bone levels, he found fewer stone tools and flakes used in the upper, most recent levels. This means a greater percentage of metal tools were being used more recently than before.

This was indeed a time of gradual transition from stone age tools to new reliance on metal.

For example each of the 5 top levels (with level 1 as the most recent, at about 1800) showed metal cut marks on the bones as well as stone marks. However the percentages clearly reveal the transition moving from stone to metal.

Near the top, in the most recent Levels, 1 to 5, he found between 100% and 63% of the bones showed gradually increasing numbers of metal cuts. While at Level 6 only 33% of butchering attempts were made by metal implements.

“An analysis for bone surface modifications can identify human made marks such as cutting, chopping and scraping associated with bison skinning, butchering and marrow processing. This analysis can show the difference between stone and metal tool marks,” he writes.

Even though researchers at Vore have as yet found no metal tools, Pierce was able to identify the various implements used from cuts on the bones. Some of the evidence required a microscope to see clearly.

“Since less than 10% of the Vore Site has been excavated, steel implements may yet be found,” he says.

Arrows can often be identified by the area they came from in trade.

All weapon points found at the Vore Site are arrow points like these. Except that all found here were broken or no longer re-workable. A broken arrow point or stone tool was found in nearly every square meter in every layer during excavations at Vore. VBJF.

“These tribes all occupied or moved through the area between approximately 1500 and 1800 AD,“ Pierce wrote in his research report ‘State Archaeologist reports on his Research at Vore Buffalo Jump.’

“Environmental changes during this time resulted in improved foraging for bison in the region, resulting in larger, more densely distributed herds.

“Taking advantage of the situation many native groups intensified their bison hunting activities. This brought a number of tribal groups living in the Great Lakes region of North America slowly moving westward onto the Plains as bison hunting took an ever increasing role in their subsistence practices.

As part of this transition these people gave up a semi-sedentary village lifestyle for a bison hunting way of life—on foot. By the 17th century Euromericans and Euromerican goods began to influence native lifeways. Native American groups began moving westward away from European settlements.

This influx of new populations had an impact on existing political alliances, hunting practices and tribal territorial claims. In some cases these movements led to conflict pushing existing populations in the region further west or south.

“This domino effect ultimately proved to be yet another factor in the migration of tribal groups into the High Plains and Black Hills during the 18th and 19th centuries.

“Part of this process involved the dissemination of the horse and gun throughout the West. The horse, gun and accompanying Euromerican goods reached the Black Hills and High Plains by at least the 18th century and were quickly integrated into native hunting and warfare practices.

“The most important result was the development of the Plains horse culture,” Pierce pointed out. “The horse brought the Native Americans a freedom of movement never possible before and many plains tribes developed a nomadic lifestyle that followed the herds.“

Stone tools transitioned to Metal in Recent bone Layers

Thus Pierce points out that the Vore site saw the transition from stone to metal tools, and it saw the transition from the bison jump method by men on foot to the introduction of the horse.

When discovered the Vore Buffalo Jump was merely a weed-covered hole in the ground. Arrow points and blades found in the Vore bone bed are mostly broken or unusable. It’s clear the good ones were not left behind, but were valued, pulled out and kept to use again. VBJF.

“The unique history of the use of the Vore site makes it an ideal dataset from which to examine this tumultuous era as this single site provides a cross section of time, in one location that researchers can use to investigate historic events, activities and processes,” he concludes 

All weapon points found at the Vore Site are arrow points. An arrow point or stone tool was found in about every square meter in every layer during excavations here.

The arrow points found in the site were those lost during butchering or were broken and no longer re-workable

Many of the stone tools found in the sinkhole are Knife River flint from quarries in North Dakota about 200 miles to the northwest. These quarries were likely controlled by the Crow during the time of Vore Site use.

The crowd joined hands around the new tipi for a prayer and Friendship dance. VBJF.

Learning to Make a Tipi

A special event took place at the Vore Buffalo Jump site in 2014 when the Foundation Board decided they needed a tipi to exhibit in one of their buildings.

Not just any tipi, but an authentic tipi from the time the Vore Buffalo Jump was being used. They had high standards. That meant it had to be small enough and light enough to be hauled by one or two dogs.

People in charge of the Vore Buffalo Jump have tried to use ancient Native American methods and authentic Native tools in their work when possible.

The buffalo hides had to be tanned in just the way women tanned and sewed them together for tipis long before they had horses. So why not find Native women to do it?

They soon found that the main expert in the art was closer than they imagined. The ancient technique was taught at Chief Dull Knife College in Lame Deer, Montana—not so very far away.

A class of Northern Cheyenne women in Chief Dull Knife College was studying just that. They had their own mission and said they’d be delighted to come, tan buffalo hides the old way and make the proper kind of tipi needed right on the Vore site itself.

In fact it would be ‘a dream fulfilled.’ The seven women who came on that mission were Larie Clown, Victoria Haugen, Lori Killsontop, Tee Jay Littlewolf, Maria Russell, Rebekah Threefingers and Jodi Waters.

The last time their community had constructed a similar tipi was around 1877 when herds of buffalo were on the verge of extinction and reservations were being established.

The Vore foundation was determined to get grant funds together and do it right. And they did.

“The 5 buffalo hides, sinews and other materials needed were expensive,” says Jackie Wyatt of the VBJF, who lives in Sundance WY.

“To bring this long-sought dream into reality required the effort of the Cheyenne workers, Larry Belitz who directed the tipi-making, and behind-the-scene work of Vore Buffalo Jump Board of Directors.”

And so the tipi was constructed on site by students accompanied by an instructor from Chief Dull Knife College under the guidance of Larry Belitz, the world expert on the technique.

The tipi made by the Northern Cheyenne women found a home in the big research building down in the sinkhole. Because the Vore Jump was used before the time of horses, the tipi, made from 5 buffalo hides, was of the smaller size to be pulled by dog travois. It weighs about 90 pounds so the travois would probably be pulled by two dogs. VBJF.

When finished, the tipi found a home in the large research building in the sinkhole, providing inspiration to researchers and volunteers as they work to excavate new layers of bones and develop new educational panels.

Reaching out to the Next Generation

Kids enjoy the BJ Bison sketches and other age-specific materials designed for them as they learn about the ancient heritage of their state and region. VBJF.

Leaders in the Vore Jump Foundation feel a special responsibility to teach the next generation of young people about their heritage. They feel certain the legacy and future of this delightful site is in the hands of 4th graders and their teachers.

The location of the Vore sinkhole near the corner of four states—Montana, Wyoming and North and South Dakota, and literally only a stone’s throw from Interstate 90—makes it very convenient for schools in the area.

The BJ Bison drawing above is familiar to youth who’ve been on the Vore tour. A number of educational materials are directed specifically to their age group—especially the 4th graders who generally study their state’s history. After that, 8th graders and high school students who take Plains history are targeted.

The off-season field trip program hosts about 1,000 students every year. The Vore Site stays open from June 1 through Labor Day in September from 8 am to 6 pm.

After that it is available for schools and off-season tours by request. Volunteers happily give tours to school kids.

A true Non-profit: Vore Buffalo Jump

The non-profit Vore Buffalo Jump Foundation board operates like a true non-profit. They have virtually no administrative costs.

Think of what that means. That many highly qualified people are contributing their talents. It’s a labor of love.

And sure enough, Jackie Wyatt tells me that 8 people living within 50 miles serve on the Foundation Board—all volunteering their time, talents, concerns and money.

Another 10 or 12 persons serve as an advisory board. These include educators, college professors and US Forest Service anthropologists, who also volunteer their services.

These people rise to the occasion when needed. Contribute their time, talents and cash to this amazingly difficult million-dollar project that suddenly dropped in their laps, only because of where they happen to live.

And when I reflect, it’s to realize this is what rural people do all the time. They get the job done. These people won’t fail in their mission. It is indeed a labor of love.

The Vore decision makers also have high standards, not to be compromised.

For example when they commissioned the construction of the tipi. They found the best talent and paid what was needed.

For the Northern Cheyenne women too, the tipi project was a labor of love. They called their assignment ‘A dream fulfilled.’ To have the rare privilege of constructing a tipi in the old way, the way it ‘should’ be done—a task their community had last completed in 1887 apparently was reward enough.

At Vore only the hired interpretive staff are paid—admission charged visitors during summer pays their salaries. The buildings and exhibits have been funded through grants and donations. The VBJF took out a loan in 2013 to put up the tipi and drill a well, which allowed them to put in restrooms.

I’m impressed and overwhelmed by their generosity and willingness to go the second mile.

In this day and age we are all too familiar with so-called “non-profits,” launched by well-meaning people, perhaps at the start. But who go on to give themselves impressive titles, paying big salaries to themselves and relatives, making sure that donations pass through their own greedy hands, till there’s almost nothing left for the cause they claim to fight for.

The Vore Jump Foundation is a polar opposite of that. It’s well worth our consideration. Dedicated people like Jackie Wyatt and Gene Gade put in many hours but do not expect or want payment for their talents and work.

For instance, Gene Gade who writes well-researched articles in the VBJT newsletter took the job as County Extension Agent in Sundance Wyoming many years ago.

He must have thought to himself from his County Agent vantage position, “‘I know how to do this; I need to help,’ and put in over 20 years as president of the non-profit VBJ Foundation.

From his great USDA Extension conections he helped to develop and guide the research, education and economic potentials of the Vore site for all those years.

Now in retirement he and his wife moved to Oregon to help a daughter with their grandchildren.

From there he still writes timely articles for the Vore Buffalo Jump Newsletter, continuing to research fresh information.

In Oregon he’s involved in working for Native American causes from a new vantage point from which he says, “The devastation of the Columbia River salmon has been as disastrous to Indigenous people of the northwest as the near extinction of bison was to the Plains tribes.”

And how much is he paid for all this? Don’t be ridiculous.

And there’s Jackie Wyatt. When the Foundation Board was required to build a railing for the trail down to the research sinkhole or be closed down, she made many phone calls and people donated what was needed. Jackie says even a 4th grade class that happened to be there on a field trip emptied their pockets and gave what they could when they heard. Isn’t that cool!

No one is getting wealthy from donations to Vore Buffalo Jump. All funds go into essentials to keep the place running, add improvements and to advance ongoing research at the site. Concerned people just donate more. That’s what is done in rural communities—it is needed and they don’t count the costs.

The Future

The Vore Foundation is actively working to establish permanent facilities with the goal of creating a world-class research, education and cultural center at the Vore Site.

Foundation leaders are quick to point out that because less than 10% of the Vore Buffalo Jump has been excavated “there is potential for decades of scientific research in several different disciplines…archaeology, tribal ethnohistory, zoology, geology, and paleoclimatic studies.

“Dozens of technical papers based on data from the Vore site have already been published. Just as the Black Hills attracted Native Americans, visitors from around the world are fascinated by Plains Indians.”

The Foundation has resolved to save the past for future generations, and we know they will.

However our admission fees and generous donations will help as they continue their research and development of this major archaeological site of the Late-Prehistoric Plains Indians.

The Vore Buffalo Jump Foundation Research, Education, and Cultural Center project does need our help. Its a true non-profit foundation that counts on donations to meet the financial requirements of their vision for the Vore Buffalo Jump.

They also appreciate Volunteer assistance and ‘in-kind’ contributions.

If you believe in this cause your support is most welcome and certainly needed. (Must admit I support these people who nourish the Vore Jump at least partly because what they are doing is exactly what I’d love to have happen in our own area of historic buffalo sites. Maybe we could build a useful, carefully accurate and active Buffalo Visitors Center that comes off as wonderful and is fully supported by the home folk.)

In rural areas this is the way people mostly get things done—whether fighting fire, running life-saving ambulances or designing tourism projects. Volunteers do what’s needed.

 And for sure, they’re the best kind. Many donations even come in anonymously! Who needs or wants credit for helping do something this good?

 The Vore Site is managed by the 501(c3) non-profit Vore Buffalo Jump Foundation (VBJF) board. I can’t help telling them each one is a hero—”You are truly unsung heroes! You get the job done!”

Meat Intake linked to Health and Longer Life

Eating red meat extends your life, scientists say, in a comprehensive new world study published Feb 22 2022 in the International Journal of General Medicine.

Has eating meat become unfairly demonized as bad for your health?

“While detrimental effects of meat consumption on human health have been found in some studies in the past, the methods and findings in these studies are controversial and circumstantial,” says study author Dr. Wenpeng You, University of Adelaide researcher in biomedicine.

“Looking only at correlations of meat consumption with people’s health, or life expectancy within a particular group, or a particular region or country can lead to complex and misleading conclusions.

“We wanted to look more closely at research that has thrown a negative spotlight on meat consumption in the human diet,” Dr. You says. Their study examined the health effects of total meat consumption in 175 countries–approximately 90% of the world.

“Our team broadly analyzed the correlations between meat eating and life expectancy, minimizing the study bias and making our conclusion more representative of the general health effects of meat eating at global and regional levels.”

This study shows that meat intake is positively associated with newborn life expectancy, life expectancy at 5 years of life and adult life expectancy.

In regard to the often praised Mediterranean diet, she says it is worth noting that their studies show countries on the Mediterranean diet have greater life expectancy when there is more total meat in their diet. This may suggest that, regardless of suggested beneficial health effects of Mediterranean diet, more total meat intake may benefit longevity in the populations primarily on this diet.

“The majority of countries bordering Mediterranean Sea are developing economics, and have high mortality rates for chronic diseases, such as cardiovascular diseases and cancers. The correlation between the Mediterranean diet and low incidence of chronic diseases might be sporadic in the studies in the populations surrounding the Mediterranean Sea because their high mortality rates have eliminated patients with chronic diseases.”

She says humans have evolved and thrived over millions of years because of their significant consumption of meat. The complete nutritional profile of meat and human adaptation to meat eating have enabled humans to gain many physical benefits, including greater life expectancy.
Meat intake, or its adequate replacement, should be incorporated into nutritional science to improve human life expectancy.

“Education is an important contributor to life expectancy similar to caloric consumption, while meat consumption has a significant effect on life expectancy at age 5 years.

“Worldwide, populations with more meat consumption have greater life expectancies,” adds Dr. You.

Meat has advantages over food of plant origin in containing complete protein with all essential amino acids, is rich in vitamins, in particular vitamin B12, and all essential minerals. It has a significant role in maintenance of better physical growth and development, optimal breastfeeding and offspring growth.

The study examined the association between meat intake and life expectancy at a population level based on ecological data published by the United Nations. All required information available was obtained for this study, which looked at total populations rather than selected groups.

The Vore Buffalo Jump—Part 1

The Vore Buffalo Jump—Part 1

Vore Buffalo Jump in northeastern Wyoming does not involve a cliff at all, but rather, a trap.

It developed when a sinkhole opened up at the western edge of the Black Hills cave system and was used as a jump to trap bison by Native American hunters for about 250 years.

When the hole was first used some 450 years ago, it was 75 feet deep and narrower than now. Today, it is about 50 feet deep and more than 200 feet across.

The buffalo bones are in 22 layers laid down one by one and are regarded by archeologists as the remains of 22 separate hunts that happened from 1559 to about 1800. An average of fewer than one hunt every 10 years. All except two were fall hunts as determined by tooth age of calf skulls found.

By the time homesteaders began to claim land in the area, there was no evidence on the surface of the sinkhole floor that this site had been used as a bison trap. As it did after each hunt, the sinkhole had blown in with silt and grassed over.

Named for the Vore ranching family who donated the land, the jump itself is a large natural sinkhole at the base of a long sloping ravine that opens out into a broad, flat valley.

It is located only 5 miles west of the South Dakota line, not far from Spearfish, SD or Devil’s Tower in northeast Wyoming and directly in the path of Interstate-90, which crosses the nation from the Atlantic to the Pacific.

An Era of Dramatic Change

The last jump at the Vore site happened sometime between 1770 and 1800. The technique was being made obsolete by the advent of horses and guns.

One of the rare and interesting things about the Vore site is that it lasted only 250 years as a buffalo jump—from 1550 to 1800.

Those were years of dramatic change for Native Americans who lived on the plains. The changes clearly played out and revealed themselves in the research coming from Vore Buffalo

The era began before the time of horses on the Plains when humans depended on dogs for transportation of their goods. Gradually there came an acceptance of European trade goods such as metal knives and guns that began reaching remote corners of the west.

Then came the flowering of an amazing horse culture that brought Native Americans great freedom of movement and established them as some of the greatest horseback riders the world has ever known.

At the same time, many tribes began moving west where they took up a nomadic lifestyle following herds of buffalo and developing a culture dependent and spiritually interrelated with them.

Thus the Vore jump tells us a great deal about who these people were, where they came from, and how they lived during that time of transition. It is being revealed by cuts in the bones and other evidence found there.

How the Sinkhole was Used

Buffalo or bison ranged from what is now Canada to Texas when the Vore Site was first used, according to the Vore manual for guides.

At that time the Native Americans way of life on the Great Plains depended on bison. Before Europeans brought the horse to the Americas, they were hunted on foot, a few at a time, or communally by driving the animals into pounds (essentially corrals) or off precipices.

At the Vore Site, the sinkhole was the trap, and bison butchering took place down in the 60-foot hole. The bones of the bison and the stone tools left by the hunters are found in the layers of sediment that make up the sinkhole floor.

“Archaeologists estimate that around 200 people would have come together for a big jump. They would have belonged to one tribe, but the Vore Site was used by a number of different tribes over a period of about 250 years,” says the manual.

“Just to the west of the site would have been good pastures, and about three and a half miles to the east were good camping sites, water and wood, along Sand Creek near what is now the town of Beulah.”

These may have been places where a tribe camped for the longer time needed to dry out the buffalo hides and make jerky and pemmican after a successful hunt.

“In the fall (after the breeding season) bulls would have wandered off and cows and calves split into small herds of 40 to 60 head.

“Late October and early November a tribe would plan a hunt. Runners would go to the far side of a small herd and worry the bison, which caused the smaller herds to gather. The bison thought there was safety in numbers. The large herd, of some 500 or more, would be worked slowly toward the trap.

“There are remnants of drivelines formed by rock cairns (similar to our replicas to the west of the sinkhole) in the pastures southwest of the site that point toward the sinkhole. The lay of the land around this sinkhole made it possible for the hunters to use it as a trap.”

Before the interstate highway changed the area, a draw provided a natural funnel leading into the sinkhole.

Hunters were stationed up along the sides and when the herd was a short distance from the sinkhole, they started a stampede.

If the bison herd was strung out running down the draw, many might have dodged around the trap down below when they came to it.

But with the full mass of bison stampeding and threatened by the sharp horns of those behind, they’d be down in the draw with the hole in front of them before they knew what was happening.

Bringing them narrowly into the hole tested the skill and bravery of hunters who clearly understood buffalo behavior. They had to keep the stampeding herd headed directly into the opening and not allow them to escape to the side. If even a few escaped, likely others would follow.

Then it was easy. Hunters gathered at the rim, shooting with lances or bows and arrows the buffalo down below not killed by the fall.

The sinkhole floor was a place of butchering. A trap with no escape.

The sinkhole was a trap with no escape, but could be dangerous with plunging, dying buffalo. VBJF.

Yet it must have been a dangerous place for hunters who entered the pit filled with dead and injured buffalo.

Then the meat had to be carried up and out or pulled up with hide ropes.

“These hunts happened before the local Native American tribes had horses. The bison had to be cut into pieces small enough to be pulled up and out of the sinkhole.  

“Most likely men did the butchering. The women probably began work in camp right away, tanning hides and stripping and drying the meat. Meat and hides and large bones would have been transported on backs and via dog travois.”

Discovery of Vore Sinkhole

The Vore Buffalo Jump was discovered in 1969 by the Wyoming Highway Department while planning Interstate-90 Highway, according to Ted Vore.

Right-of-way purchased from the Vore Ranch encroached approximately 30 ft. over the edge of the sinkhole.

Highway engineers were concerned about gypsum sinkholes that might affect the stability of the highway and asked permission to build a road down into the sinkhole and drill.

Woodrow Vore, Ted’s father, suggested they drill up where the road was to be as gypsum sinks could be anywhere.

They trespassed anyway, bulldozed a crude road into the sinkhole, and sent a truck with an auger to check out its floor.

Wherever they punched a hole, they encountered buffalo bones within a few feet of the surface. Clearly this was an archaeological site, but the construction leaders would have preferred to keep quiet about the discovery and continue building the highway as planned.

Wherever they punched a hole the engineers brought up buffalo bones close to the surface. Cross trenches were dug to a variety of depths and investigated. VBJF.

However, an engineer on the crew blew the whistle and contacted George Frison, who at that time was a professor at the University of Wyoming, later to become Wyoming State Archaeologist, reportedly bringing with him a box of buffalo bones from the site.

Frison went to the Wyoming Department of Transportation and convinced them the site must be investigated. The story told is that Frison dumped the box of bones on the DOT director’s desk.

As he hoped, the decision was made to move I-90 a few hundred feet south and do an archaeological survey of the sinkhole.

Frison received permission from the Vores to excavate the bottom of the sinkhole to find the extent of the bone bed. During the summers of 1971 and 1972, excavations by Frison, his staff and students discovered that the bone bed covered the entire floor of the sink hole.

These first archaeologists also dug a shaft that went down about 25 feet. They discovered 22 layers of bones—each the remains of a single jump.

The Vore Buffalo Jump Foundation was locally formed as a vehicle to help the University in site development.

Unfortunately, you can no longer see the bones they dug up. When they left in 1972 they back-filled the trenches and shaft to protect the remaining artifacts. As they left, the team took about 4 tons of bones and many stone tools with them to the U of Wyoming to study.

In the fall of 1989, the Vores deeded the site to the University to be developed as strictly an education and research facility. The University was given 12 years to develop the site and open it to the public.

In the 12 years the University conducted studies and used the site for archaeology field school activities. However, they made no progress toward opening the site to public viewing. The excavation was covered up and nothing more was done.

Working the bones. Excavation work resumed in 1995. Crew includes archaeologists, students and volunteers. VBJF.

Since the University did not meet the deed restriction of 12 years, the site was deeded back to the Vore Ranch and immediately deeded to the Foundation.

Excavation work began again at the Vore Jump site in 1995. The bones seen in open excavation units are from hunts that occurred from the mid to late 1700s—in other words, the most recently butchered.

The first hunt at Vore was in 1559, according to the experts. It is still deeply underground.

What caused the Sinkhole?

“To understand Black Hills geology generally and the Vore site sinkhole specifically, one needs to understand some properties of gypsum and limestone,” write Megan Schnorenberg and Gene Gade in their article ‘Geology of the Vore Buffalo Jump.’

We do not know when the Vore Site sinkhole formed but it was presumably hundreds of years before it was first used as a bison trap. Sinkholes result from the collapse of the roof of a cave formed in the underlying rocks.

Throughout the Black Hills rocks such as limestone or gypsum are dissolved by ground water to form caves. Both these types of rock are visible here at the Vore.

Sinkholes may be dry, as is the case at the Vore Site, or filled with water as observed a few miles to the east in South Dakota at the McNenney Fish Hatchery at Mirror Lake.

At Hot Springs, in the southern Black Hills, a sinkhole in the Spearfish Formation was the spectacular death scene for over 60 mammoths and is now the Mammoth Site and Museum, a popular tourist destination.

The formation of the sinkhole is related and similar to the caves that are interconnected throughout the Black Hills. Some have water and springs; some are dry.

Gypsum and limestone have in common the fact that both contain positively charged calcium ions. They differ in that the predominate negative ion in gypsum is sulfate (SO4) while the negative ion in limestone is carbonate (CO3). Both gypsum and limestone are somewhat soluble in water, but water can only hold a certain amount of either of them in solution. Gypsum is more soluble than limestone so gypsum usually dissolves first when they are in water together, according to the authors.

The opposite is true when they settle out of the water solution or ‘precipitate’ back into a solid—i.e. lime will precipitate before gypsum. Both are less soluble than some other compounds that are commonly dissolved in water, such as table salt (sodium chloride or NaCl).

When a body of water that contains all three compounds starts to evaporate (as in a shallow sea, desert lake or swamp), lime will precipitate into a solid first, then gypsum and, finally, salt.

If water returns the system later, they’ll generally dissolve in the opposite order . . . salt first, then gypsum, then limestone.

In the Black Hills, the Madison Formation formed from shells and dissolved calcium carbonate precipitated out of an ancient shallow sea, forming limestone. However, within the limestone, were lenses of gypsum.

Over time, cracks formed in the limestone and gypsum layer. Groundwater filled the cracks. The gypsum dissolved away leaving cavities in the limestone.

Additional water, combined with organic acids the water picked up as it soaked into the ground and percolated into fissures in the rock, dissolved some of the limestone.

The result is some of the largest caves in the world. Wind Cave in the Black Hills is not only one of the longest cave systems in the world—140 miles explored, the sixth longest cave—and is also the most dense (passages per mile) in the world.

Wind Cave has 95% of the world’s discovered boxwork rock formations, which are thin blades of calcite that project from the cave walls or ceilings. It is a sacred site for the Lakota people, as creation stories say this is where their people emerged from the earth, according to the Black Hills Visitor.

Jewel Cave has 132 miles surveyed and is also one of the world’s longest.

“About 60 million years ago, igneous (molten) rock pushed up and formed the bulge that ultimately became the Black Hills. During this uplift, the overlying sedimentary rocks (limestones, sandstones, shales, etc.) were tilted up.

“Eventually most of these overlying sedimentary rocks eroded away from the highest points in the Hills, leaving the granite core exposed in places like Terry and Harney Peaks.

“Erosion exposed the no-longer horizontal sedimentary layers around its flanks. These exposed sedimentary rocks on the so-called ‘limestone plateau’ are now the primary ‘recharge areas’ where water enters formations like the Pahasapa-Madison and Minnelusa Limestone formations.

Each building houses exhibits on the hunters who used the site, how they jumped the buffalo and used the meat and hides. And the dogs that traveled with them. VBJF.

“Once in the rocks, the water flows downhill through fissures creating considerable gravitational pressure on this groundwater at lower elevations around the base of the Black Hills.

“Due to pressure, water from underground aquifers will flow upward into overlying strata if it can. If the water reaches the surface, the water will form a spring or artesian well, thus relieving the pressure.

“Major springs such as those that create Sand Creek (a perennial stream 3 miles east of Vore Jump) are an example. However, if, on its path to the surface, the pressurized groundwater passes through rock that is particularly soluble, a cave may form.

“That is exactly what the current theory suggests in the Vore Buffalo Jump sinkhole. U.S. Geological Survey geologist, Dr. Jack B. Epstein, who has been studying the Spearfish Formation sinkholes believes that the Vore Buffalo Jump sinkhole did not result from a collapse directly into a large cave in the underlying limestone.”

Rather, says Epstein, pressurized water in the tilted limestones rose through fissures until it reached the soluble gypsum at the base of the Spearfish formation.

“The gypsum dissolved, creating a solution cavern near the surface. The overlying ‘red bed’ sediments then collapsed at points into the void where the gypsum used to be, creating the Vore site sinkhole and others (such as the one just north and west of it).

“If the bottom of the new sinkhole is above the ‘potentiometric surface,’ (the level to which water in an aquifer would rise due to the natural pressure in the rocks), then the sinkhole is dry, if not, the sinkhole will contain a spring.”

“The sinkhole which is the focus of the Vore Buffalo Jump is surrounded by several gypsum beds, each 8-10 feet thick.

“Although no gypsum is present in the current bottom of the sinkhole, gypsum veinlets can be seen in the walls of the sinkhole, and are probably a result of the expansion of the gypsum and fracturing of the surrounding rock.

“The layers of bone which are found to extend 20 feet below what is now the natural bottom of the sinkhole indicate that sediment was rapidly deposited over the 300-year use of the sinkhole,” Gade and Schnorenberg report.

The Vore Buffalo Jump Foundation

All buildings and development of the site today has come through the efforts of the VBJ Foundation.

Three buildings currently make up the Vore Site. A small cabin serves as a place to greet visitors. The tipi on the sinkhole rim houses exhibits and restrooms.

The building on the sinkhole floor covers open excavation units where the work continues. Each building houses exhibits on the hunters who used the site, how they jumped the buffalo and used the meat and hides and the dogs that traveled with them.

Visitors see bones, not fossils. The floor is a work in progress, ongoing active excavations. VBJF.

What visitors see are bones, not fossils. This is not a museum exhibit but an active excavation. The bones in the unit on the southwest corner are from the very last hunt at the Vore Site and are about 250 years old.

This is essentially the garbage left behind after the butchering was completed.

“The Vore Site is managed by the 501(c)(3) non-profit Vore Buffalo Jump Foundation (VBJF) board. All board members are volunteers,” according to their website www.VoreBuffaloJump.org

“We have virtually no administrative costs. The admission charged visitors during the summer season pays the salaries of the interpretive staff. The buildings and exhibits have been funded through grants and donations.

“The VBJF took out a loan in 2013 to put up the tipi and drill a well, which allowed us to put in restrooms.

The Vore Site is open to visitors in summer (June 1-Labor Day) and off-season to school field trips by appointment. VBJF.

“The Vore Site is open to visitors from June 1 through Labor Day (8 am to 6 pm). The off-season field trip program hosts about 1000 students each year.”

8th White Bison born to Herd at Sioux Valley Dakota Nation

8th White Bison born to Herd at Sioux Valley Dakota Nation

With a new white bison calf joining the herd in Sioux Valley Dakota Nation, community members say it’s a sign to get back to living in balance with nature.

 The calf born on April 16 is the eighth white bison to be born on the First Nation in as many years. They are part of a herd of 104 bison in the community about 40 kilometres west of Brandon, Manitoba.  

 “The white buffalo is a blessing and a warning for our people, not just Native people but all people,” said Kevin Tacan, one of the community’s spiritual advisors, whose family also takes care of the herd.

 Tacan said climate change is noticeable not only to us, but to animals as well

 “They’re starting to come back, reminding us that we’re supposed to be living in balance with nature,” he said.

 “We’re supposed to be living in balance with the animals and the natural world, and we’re not doing that.”

 Tacan said First Nations have a special relationship with bison.

 “We have a very close, spiritual relationship with the buffalo, because we both experienced genocide,” he said.

 “And right now we’re getting our apologies from governments, but there are no apologies coming for the buffalo herd yet, and it’s something we’d like to see down the road.” 

He said the bison are there for community members and other folks who come and pray. 

“They pray for relatives who are sick or who are struggling in life with addictions or anything like that,” he said.

“They’re all different tribes that are coming here and doing their ceremonies here.”

Tobacco offerings tied in colourful fabrics line the fence, left by previous visitors. 

“The buffalo would come and check them out, and listen to their prayers and then hopefully they’ll carry our prayers for the year, so that we can live a healthier, happier life,” said Tacan. 

Keeping the herd wild

Tony Tacan, Kevin’s brother, is the community herd rancher, and a council member.

He said this is the second bison herd they started after being given a white bison by the Assiniboine Park Zoo in Winnipeg in 2010. 

His family takes care of the bison, along with their horses. 

“We took the responsibility on for the community, to ensure that they’re fed, watered, cared for,” said Tony Tacan. 

“We’ve been doing that for so many years now.”

He said his brothers and cousins help out, along with his sons and nephews. 

“We expect to keep them wild, we don’t want to domesticate them,” he said.

“That’s not the way of our people.” 

Tony Tacan said there will be upcoming changes to the area, with a cement pad created for the elders’ handi-van, and signs on the main road directing people to the compound. A space for gatherings is also in the works. 

“We make sure we have a place for people to come and pray; it offers people hope,” he said.

“Times being what they are, we need them to come here and feel better.”

Body Condition Scoring Guide for Bison

Body Condition Scoring Guide for Bison

Canada has developed detailed national guidelines or Codes for the care and handling of farm animals, including bison and poultry. The Codes serve as the national understanding of animal care requirements and recommended practices.

The writers of these codes come together from a wide background of experience in studying and handling specific animals. They meet together and make decisions on what Canadian recommendations should be for each species.

Roy Lewis, DVM, is a veterinarian who served on the committee for the updated 2017 Canadian Code of Practice for the Care and Handling of Bison. The decision makers of these codes come from a wide background of experience in studying and handling buffalo.

Dr Roy Lewis, an Alberta veterinarian who has worked with bison many years and served on the committee updating the National Canadian “Code of Practice for the Care and Handling of Bison,” sent me links to the Canadian bison codes.

He is also helping plan the International Bison Convention to be held in Saskatoon, Saskatchewan, July 12-15, 2022, and has served as a part-time technical services veterinarian for Merck Animal Health.

The Code of Practice for the Care and Handling of Bison was released in 2001 and updated in 2017. In Canada, scoring bison in your herd is considered an important management tool that allows ranchers to monitor and evaluate their feeding programs—and to adjust as needed.

The following comes from Appendix C of the Canadian code which discusses Body Condition Scoring. Much of this is adapted from What’s the Score: BisonBody Condition Scoring Guide from Alberta Agriculture.

Bison Body Condition Scoring

Body condition scoring (BCS) is a method of assessing the amount of fat cover on an animal, Since hands-on examination is impractical with bison the 5 point system for bison uses primarily visual clues.

The BCS system is a 5-point scale where a score of 1 means that the animal is extremely thin or emaciated and a score of 5 means that the animal is very fat. 

Bison’s nutritional requirements and feed intake vary with day length/season

A certain amount of weight loss is expected over the winter months. However, to accommodate this winter weight loss, bison need to be in good condition in the fall. Adult bison should not lose more than 1 to 1.5 body condition score during the winter feeding.

This table outlines target BCS for different classes of bison at different times of the year, generally scoring 3 to 5.

Table C.1 – Seasonal body condition score targets for breeding herds1

There are several features of bison anatomy that make condition scoring bison different from scoring cattle. Special attention is given to the hip bones, rump and hump.  

Body condition scoring should be performed using a consistent procedure by an experienced person or one who has been mentored in the process. Evaluate the key landmarks of the hump, ribs, spine, hip bones, rump and tail head, and then take in the overall appearance of the animal.

Consider factors such as hair coat and the animal’s age, and then record the score on a 1 to 5 scale; half points (2.5/5) or a range (2–3/5) may be used, especially if the scoring is visual only.

All animals should be evaluated and scored if possible, or if that is impractical, a large cross-section of each class of animal in the herd should be scored. Determine the average for each class and note any particularly thin or fat animals.

Adjust feeding and management as necessary in order to meet BCS targets and take corrective action for individuals outside of the target ranges. 

What’s the Score?

BODY CONDITION SCORING CAN HELP BISON producers manage their herd for optimal health, production, and profitability. Body condition refers to the amount of fat that an animal is carrying. Body condition scoring is designed to estimate the amount the fat the animal has. It is a useful management tool that helps farmers and ranchers do a better job feeding their stock.

BODY CONDITION SCORING SYSTEMS

THE FIRST BODY CONDITION SCORING SYSTEM was developed for sheep because producers could not determine how fat or thin a ewe was when she was in fleece. The manual palpation method for determining BCS was developed to overcome this problem. This system was later adapted for use with beef and dairy cattle and later for bison.

The system presented for bison in this article has been adapted from the beef and dairy cattle 5 point scale. A body condition score (BCS) of 1 indicates that the animal is very thin. A BCS of 5 indicates that it is very fat. Since bison are seldom caught in a squeeze to allow a “hands on” body condition scoring system, most of the criteria used to assess the animal are visual clues.

While learning how to body condition score bison, it is helpful to feel the bison in a squeeze so that you can feel what you think you are seeing under their thick hair coat. Once a person is experienced in scoring bison, visual clues are adequate.

TARGET CONDITION SCORES 

IDEAL CONDITION SCORE DEPENDS ON THE TIME of year. Over the different seasons of a year it is normal for a bison’s weight and body condition score to fluctuate. Most people aim to have their bison fat in the fall so that they do not require as much feed over the winter.

Most experienced producers aim to have their bison lean in the spring because excess fat may lead to calving problems. By the beginning of breeding season, the cows should be back to a moderate to good body condition to ensure optimal conceptions rates.

TIME OF YEAR IDEAL SCORE RANGE

November 4 3-4+

April 2+ 2-3

July 3+ 3-3+

By knowing your herd’s body condition score, you can adjust your feeding to meet the above targets. If the animals are too thin, increasing the amount or quality of feed and supplements will increase their body condition score. If the animals are too fat, the opposite is possible and money can be saved in the winter feed bill.

One must be aware that any change in BCS should be gradual as rapid changes, either up or down, can cause health problems.

Rapid weight loss in fat bison can precipitate a disease called “Fatty Liver Syndrome” and cause death. Rapid weight gains on grain diets are possible but this type of diet can cause digestive upsets and may cause death as well.

BCS AND BODY WEIGHT

IN BISON, ONE UNIT OF BCS IS ROUGHLY EQUIVALENT TO 90 pounds of live tissue weight. The approximate composition of this tissue would be 70% fat, 24% water, 6% protein and 1% mineral (adapted from dairy cow research by Otto and co-workers, 1991).

BCS AND REPRODUCTION

EXPERIENCE INDICATES THAT COWS THAT ARE too fat at calving (BCS >4), were more prone to reproductive diseases such as difficult calving than cows with lower BCS. Cows that are thin (BCS<2) experience reduced fertility.

WHY DO I NEED TO LOOK AT MORE THAN ONE AREA ON THE BISON?

There is variation between animals in how they deposit fat. Factors such as age, sex, subspecies differences, and even individual animal variation will affect the score that they exhibit at each of the scoring areas of the body. By scoring several areas and averaging the scores we get a much more accurate overall body condition score for the animal than just using one area. For example an old bison cow may look like a BCS of 2 when looking at her ribs but the other areas indicate that she is a 3. This cow would get an overall score of 3. The table can be used to score bison in the field.

OFTEN AN ANIMAL BEING EVALUATED DOES NOT meet the exact criteria of a given BCS but falls somewhere between 2 scores. The evaluator can assign them a value with a “+” sign which indicates that they are slightly more than the score given but not at the level of the next score. For example a cow scoring between a BCS of 2 and a BCS of 3 may be scored as a BCS 2+.

For further information about Body Condition Scoring see What’s the Score? Body Condition Scoring for Livestock DVD and PDF materials (available from Alberta Agriculture at: www.agric.gov.ab.ca/app08/ppsropintheweb?PubID=100031). 

Dr. Lewis comments

Of course, after studying all this, I had a few more questions for Roy Lewis, DVM, and of course he has more points to make. He’s a believer in this.

How hard is it to learn how to score—are most bison ranchers able to figure it out?

“With bison we’re usually looking at various spots over the animal tail head and transverse processes on the spine, at a distance, so we get a pretty accurate but a rougher idea than with cattle. Bison always look thinner than cattle and that is fine.”

Should the herd score similarly or is there a wide variation in conditioning between the best and worst even in one herd?

“As with any herd we’re always going to get variation–some a little over-fat, some a little thinner but we hit for the average. The thinner ones could indicate clinical disease, age or being low on the pecking order.”

What about those big shedding sheets of hair that hang on many buffalo for so much of the summer—don’t they get in the way of seeing what’s going on? 

“The shed is an interesting one but for those that have still a massive sheet into the summer there is something wrong, such as parasites or malnutrition.

“For example in the Code 1 under Body Condition the lower right-hand picture was one of a heavily parasitized bison yearling of a client. You can see the shed is still pretty much intact in June. This person was losing bison to parasitism and once they cleared that up and the shed was removed they were slick and pretty easy to body condition score.“

How about owners who might be sensitive about how their animals rate? Do they really want to know if it’s not so great?

“Owners should have no issue rating their bison because this is helping them see how their feed program is working. Body condition will hurt the performance, but also the reproductive rate, so it definitely affects profitability.

“Bison will look after themselves,” Dr Lewis concludes. “But if feed is short we need to supplement.” 

BODY CONDITION SCORING WORKSHEET FOR BISON

Make a chart with the following headings:

DATE____________

TAG #              RIBS        SPINE        HIB BONE     TAIL HEAD        HUMP           OVERALL

Assign score (1-5) to each body area for each animal. Then average numbers for an overall score for each animal.
