Flaked Stone Tool Patterning as a Means for Inferring Fremont Obsidian Procurement and Exchange

The Hunchback Shelter (42BE751 ), located in the southeastern Great Basin, yielded a considerable amount of data on the prehistoric use of the site. Located adjacent to the Wild Horse Canyon and Schoo Mine obsidian sources, evidence indicates that Hunchback Shelter functioned as a camp where Archaic to Formative (Fremont) knappers produced both bifaces and expedient flake cores. The intent of these procurement visits appears to have shifted over time. Furthermore, the Fremont visits appear to be consistent with comparative evidence from Five Finger Ridge, a major Fremont village. These findings have important implications for understanding the relationship between procurement behavior and settlement structure, and the relative importance ofbiface versus core technologies during the Fremont period.
