Bison were an important part of prehistoric life, a major component of human diets, customs, clothing and hunting patterns. Bones have been found throughout much of North America, but never in the Eastern Pecos region — a desert area that includes Big Bend National Park. Archaeologists hypothesized the bison may not have been able to cross the Pecos River.
Yet, they were perplexed by accounts from early Spanish expeditions that described native peoples using buffalo, said Sam Cason, a project archaeologist with Sul Ross.
