Abstract
The Borax Lake Pattern represents a unique pattern of technological organization found throughout northern California during the early/middle Holocene. The technological organization of the stone tool assemblage is thought to reflect a residentially mobile montane adaptation to specific environmental conditions, producing more intensive use of high elevation areas relative to subsequent archaeological patterns. This thesis defines this lithic industry through an assessment of the technological structure and ecological setting of five assemblages in three localities representing the Borax Lake Pattern in far northern California. The project reveals variability in both the diversity and use parameters of assemblages that appear to correspond with certain paleoclimatic conditions. Results provide a fuller understanding of the settlement/subsistence systems of people inhabiting northern California during the early/middle Holocene.
