Abstract
The presence of chert in mid-Holocene lithic assemblages along the Snake River has been attributed to long distance mobility, with the material introduced in bifacial form to the canyons from upland quarries. Geological field studies, however, show that chert, argillite, and quartzite are common in terrace and alluvial gravels along the lower Snake River. These lithologies probably provided a major source of high quality raw material for populations wintering near the river throughout the Holocene.
