Archaeological Investigations at Site 45-DO-326, Chief Joseph Dam Project, Washington.
Abstract
Site 45-DO-326 is a rockshelter on the south bank of the Columbia River about 100 m upstream from River Mile 559. Vegetation is characteristic of the Upper Sonoran life zone. The University of Washington excavated 89 sq m (12.5%) of site volume in 1979 for the U.S. Army Corps of Engineers, Seattle District, as part of a mitigation program associated with adding 10 ft to the operating pool level behind Chief Joseph Dam. A systematic sample of 1 x 1-m units was laid out in the area outside of the rockshelter and an elongate block excavation was undertaken within the area of the basalt erratics. Four zones of cultural occupation were defined within a complex stratigraphic record about 1.5 m in depth. Radiocarbon dates and diagnostic projectile point types document at least 5,000 years of cultural activity spanning all three cultural phases defined for the Rufus Woods Lake project area. The rockshelter was maintained as a hunting base camp during the latter part of the Kartar Phase (ca. 5000-4000 B.P.).
