Preliminary Appraisal of the Archeological Resources of Onion Flat, Soral Creek, and Raft Lake Reservoirs, Big Horn River Basin, Fremont County, Wyoming

Archeological Investigations of the proposed Onion Flat, Soral Creek, and Raft Lake reservoirs, in the Big Horn River Basin, Fremont County, Wyoming, were made in June and July, 1949, by the Missouri River Basin Survey, Smithsonian Institution, The reservoirs are irrigation projects of the Bureau of Reclamation (see map accompanying this report), The surveys, made in accord with the memorandum of understanding between the Smithsonian Institution and the National Park Service, were undertaken in order to discover any archeological remains in the future pool areas and to determine whether there are sites of major importance in these areas which should be excavated prior to the filling of the reservoirs. Preliminary topographic maps of the Onion Flat and Soral Creek reservoirs were furnished by the Bureau of Reclamation, Road maps of Fremont County, Wyoming and of the Wind River Indian Reservation were used in exploring the Raft Lake Reservoir area. The work was done by Richard P. Wheeler, archeologist, and Neil J. Isto, student helper.
