Both prehistoric and historic Native Americans were hunting bison at or near the sites. B. Robert Butler interprets the distribution of bison bone as evidence that the bison were attacked by the hunters on the plateau above the cliff face and were driven off the cliff to their deaths. He estimates that there were about 20-30 animals killed although the bone was so badly decayed that no precise count was possible. A fire hearth was uncovered nearby but there was no direct evidence of cooking or any other activities taking place at the site. In adjacent Quill Cave there were animal bones from other species including sage grouse, rabbit, rodent, coyote, wolf, mountain sheep, and some mussel shells. However, it appears that these were likely dragged into the cave by non-human predators.
