Abstract
The Summer 2019 Central Washington University field school and Central Washington Anthropological Survey excavated four 1x1 m units at lower Sentinel Springs (45KT297) for the US Army Yakima Training Center. The stratigraphy of Units 2 and 4 were documented and bulk sediment samples were taken for each stratum. Unit 2 was excavated in 10 cm levels to 120 cmbd and a bucket auger was used to collect samples to a depth of 386 cmbd in arbitrary levels. A bone from 61 cmbd is dated to circa 2,200 years ago. Data for texture, color, magnetic susceptibility, and debitage are compared for each sediment sample (n=34). The results indicate varying depositional processes working at Sentinel Springs and buried soil horizons associated with three major episodes of climate change.
