Studies similar to this were previously performed within Caltrans districts 1, 3, 6/9, and 10, which include the southern Sacramento and San Joaquin valleys (Meyer and Rosenthal 2008 Rosenthal and Meyer 2004), the southwestern Great Basin and northern Mojave Desert (Meyer et al.

This is the fourth in a series of geoarchaeological investigations conducted for Caltrans designed to address the relationship between late Quaternary landscape evolution and the structure and visibility of the archaeological record. The following geoarchaeological investigation was implemented as part of the inventory to provide Caltrans with baseline information on the potential for buried archaeological resources along rural road segments.
Transformations in tools and technology, shifts in dietary habits, migration and regionalization, and trade intensification are all elements of Late Paleoindian-Early Archaic cultural responses to rapid climate change. Results indicate that climatic and environmental change at this interval was rapid or abrupt, and of a magnitude that likely produced varying adaptational responses by peoples of different cultural traditions who appear across the region at this period. The primary purpose of this exercise is to consider the potential ways in which climate change at the Pleistocene-Holocene Boundary affected cultural development for Late Paleoindian-Early Archaic peoples in the Pacific Northwest. This study compiles and analyzes glacial, palynological, faunal, and stratigraphic/geomorphological proxy datasets for climate change in the Pacific Northwest of North America and compares them to the coeval archaeological record. 12,600-10,200 cal B.P.) and cultural responses to attendant shifts in the environment remains a vexing issue for archaeologists. The relationship between climate change at the Pleistocene-Holocene Boundary (ca.
