The Bouchier Cache: ABiface Cache from the western Rolling Plains of Texas

The recovery of a cache of lithic bifaces (the Bouchier Cache) is reported from an ecotonal area located between the southern High Plains (Llano Estacado) and Central Lowlands (western Rolling Plains). The homogenous nature of the bifacial cores suggests that the cache represents a resource stockpile, and, therefore, is important to understanding hunter-gatherer logistical mobility strategies on the southern Plains. Bifacial core caches are a distinctly recognizable component of caching behavior that do not appear to be restricted to particular cultural groups, time periods, or geographic locations. The age and cultural association of this cache is not known. Morphological and technological examination suggests the cache would fit well with models of high residential mobility typically attributed to early and middle Holocene populations.
