The cliff above the sites would have been an excellent place over which to drive bison grazing on top. The bison, upon hitting the bottom and taking an avalanche of rocks with them, would then be shot and butchered. Archaeologists have found small side-notched points, typical of the peoples of the late prehistoric and early historic in Idaho, as well as tiny glass beads. They also found scrapers for dressing hides, as well as knives used for butchering. Quill Cave is not suited for long-term occupation, and evidence of human occupation is limited to the earliest layers of excavation, and does not appear to be related to the bison kill site, nor contemporaneous with it. It was most likely a carnivore den.
