Ethnomalacology and Paleoecology of the Round Butte Archaeological Sites, Deschutes River Basin, Oregon

28 pagesThis report is based upon a study of the molluscan material recovered from twelve sites excavated by field parties from the Anthropology Department, University of Oregon, in the Middle Deschutes River Basin in Jefferson County, Oregon, in 1961 and 1962. The Deschutes River, one of the principal tributaries of the Columbia, enters that stream about 15 miles above The Dalles and about 95 miles from Portland, Oregon. The archaeological sites are located in Sections 22 and 27, T. 11 S., R. 12 E., (Willamette Meridian), approximately 120 miles above the mouth of the Deschutes River near the confluence of the Crooked and Metolius Rivers with the Deschutes. In addition to specific determination of the mollescan material, anthropologists were interested in two problems : ( 1) information the mollusks might yield on the problem of the ecology of the region during the period of time represented by the Round Butte deposits, and ( 2) consideration of some questions relating to the interaction of mussel and human ecology
