The data in this report are presented in terms of previous archaeological research; a culture sequence concerned with man's prehistoric activities; ethnographic data on the aboriginal inhabitants of the study area; ethnohistorica1 information; a narrative history and a needs and recommendations section for future management. This compilation and presentation of cultural resources information will, hopefully, educate and encourage long term planning that will result in the conservation and protection of a non-renewable portion of America's heritage. The Coleville/Bodie and Benton/Owens Valley Planning Units, as defined by the BLM, cover approximately 1.2 million acres (750,000 acres public land, 450,000 acres private land) of variable terrain in Inyo and Mono Counties, California. The planning units are bounded in part by the State of Nevada on the north and east with the foothills of the Sierra Nevada mountains, more particularly the Inyo National Forest, on the west. The eastern boundary is the Inyo National Forest and the slopes of the Inyo and White Mountains. California State Highway 190 forms the southern boundary.
