The arrowheads and pottery suggest that at least two different groups of people camped at the cave. One style of arrowhead, the Desert Tri-notch, along with gray-ware pottery suggest that ancestral Northern Shoshone used the site; and the other style of arrowhead, the Avonlea, suggests that a group from the Northern Great Plains visited the site. Interestingly, the obsidian used to make the two styles of points is also different: all the Desert Tri-notch points are made of obsidian found far to the south near Malad, Idaho; and the Avonlea are made of obsidian found far to the northeast near the Continental Divide separating Idaho from Montana (although a few were made of the local obsidian found around Big Southern Butte).
