Clovis points along the Snake River occur near the end of the anadromous fish runs at Auger Falls and on the upper Snake River plain between American Falls and Bannock Creek. However, before the discovery of the Copper Creek example described here, they were not known to occur in anadromous, high energy, streamside locales as far downstream as Hells Canyon. The Copper Creek specimen is an impact fractured Clovis point made from Gregory Creek obsidian, which outcrops 150 km. to the southwest. This source joins Timber Butte, Big Southern Butte, and the Walcott Tuff as the earliest obsidian sources exploited by Paleoindians along the middle Snake River.
