Prehistory

“I knew we had to do something really quick. I was ready to lay down in front of a probably D17 [bulldozer] to stop that thing,” said George Frison, head of the anthropology department at the University of Wyoming. Read about the artifact-rich archaeological site Frison was prepared to defend: Powars II at Sunrise, Wyoming.

Longtime University of Wyoming archaeologist George Frison’s thinking about ancient bison kill sites was deeply informed by his early life as a hunter and rancher. Over a long career Frison won the affection and respect of students and colleagues; his many awards included election to the National Academy of Sciences.

Wyoming’s trails, roads and highways follow centuries-old Native American hunting and trade routes. For generations, Shoshone, Arapaho, Cheyenne, Ute, Lakota and Crow people gathered plants, visited family and tracked game along watercourses and over mountain passes in the seasonal subsistence patterns of their lives.

The Bighorn Medicine Wheel and its surrounding landscapes on Medicine Mountain in the northern Bighorns make up one of the most important Native American sacred sites in the United States. Twenty years of compromise and conflict on how best to preserve the site involved several governmental agencies and elders representing 16 tribes.

The Mountain Shoshone, sometimes called Sheepeaters, lived at high elevations in what’s now northwestern Wyoming from prehistoric times down through the mid-1800s. Recent archaeological discoveries shed increasing light on the lives of these peoples, ancestors of some of today’s Eastern Shoshone.

Recent, surprising discoveries including a prehistoric village in the Wind River Range above Dubois, Wyo., suggest humans—most likely ancestors of today’s Shoshone people—lived high-mountain lives as long as 10,000 years ago. 

Before any contact with Europeans, Shoshone, Crow, Arapaho, Comanche, Cheyenne, Ute and Lakota people in what’s now Wyoming bartered with each other and more distant tribes for food, horses, guns and more in trade networks stretching from the upper Missouri to the Pacific and from Mexico to Canada.  

The White Mountain Petroglyphs in the Red Desert north of Rock Springs, Wyo., feature hundreds of images carved into a rock face between 1,000 and 200 years ago. The site is on Bureau of Land Management land, and is open to the public.

The Vore Buffalo Jump, a natural sinkhole where ancient tribes drove bison to butcher them, now lies adjacent to I-90 near Sundance, Wyo., and is open to the public during the summer.

The mystery surrounding the Pedro Mountain Mummy, discovered in the 1930s about 60 miles south of Casper, Wyo., by two gold prospectors, continues to intrigue people. While some sensational media accounts indicated the mummy might have been one of the little people of American Indian folklore, scientists who studied the artifact in detail have concluded that the mummy was an infant who died because of a congenital defect.
