Archaeological Evidence for Bighorn Sheep in the Portland Basin

The Burnett Site (35CL96) in Lake Oswego, Oregon, has yielded important information about settlement, subsistence, and lithic technology in the Portland Basin during the Early Archaic. The lithic assemblage is dominated by Cascade-style projectile points, but also contains a high percentage of bifaces and expedient flake technology. The identification of bighorn sheep (Ovis canadensis) blood residues on both hunting and processing tools from the site provides new data about the resources used by early Archaic hunter-gatherer groups in the region as well as changes in animal habitats, suggesting drastic paleoenvironmental shifts have occurred in the northwest Willamette Valley between the Early and Middle Holocene.
