Abstract

Despite nearly 40 years of testing projects on the Yakima Training Center, there remains little understanding of human adaptations and subsistence patterns through time in the Yakima Uplands. Additionally, there is a need for a managerial testing review. Assemblage data from fifty-one discrete components spanning the Holocene allowed an economic site type model to be built. Results indicate a shift towards intensive upland resource procurement systems beginning 2,200 cal B.P. Assemblage artifact dimensions do not correlate with Site Type but do reflect expected changes associated with a transition from forager to collector systems. Assemblage data only appear complete at 10m3 volume sampled. Radiocarbon records indicate cultural samples are heavily skewed towards post-2500 B.P. Geologic samples are more evenly distributed, with gaps likely attributable to depositional processes. Managerial recommendations for future testing and research were developed from the above analyses.
