Historically the Middle Fork of the Salmon River was occupied by the Sheepeater Shoshone and all indications from the styles of recovered artifacts, primarily the spear and arrow points and the pottery, is that Shoshonean ancestors periodically used the site for over 3000 years. Not only are the artifact styles consistent with Shoshonean occupation but the materials used to make many of the artifacts are not locally available but originate far to the south along the Snake River Plain. This suggests that people probably wintered on the Snake River Plain and traveled into the Salmon River Mountains carrying the material they might need while camping in the Mountains and left the material behind when they journeyed back to the Plain in the fall.
