Cascade Points in the Northern Great Basin: A Radiocarbon-Dated Foliate Point Assemblage from Warner Valley,Oregon

Although common in the northern Great Basin, foliate points sometimes referred to as Cascade points are generally regarded as poor temporal markers because they are found in early, middle, and even late Holocene contexts. It is unclear whether this broad timespan is a function of prolonged use of the point form, later groups recycling discarded artifacts, or a combination of both. We review the spatial and temporal distribution of foliate points in the northern Great Basin and present new data derived from work at a stratified rockshelter in Oregon's Warner Valley. There, we have uncovered foliate projectile points that meet the original definition and more recent refinements of the Cascade point type associated with a late early Holocene and middle Holocene occupation. We present technological and source provenance data for the points and the associated lithic assemblage and reconstruct how prehistoric foragers used the rockshelter.
