Archeological Progress Report No. 13, Field Season of 1968

This is the thirteenth in a series of annual reports summarizing current field and research activities of the Smithsonian Institution, River Basin Surveys, under the auspices of the Inter-Agency Archeological Salvage Program. Smithsonian River Basin Surveys operations continued throughout 1968 at the Lincoln headquarters and two parties were fielded during the 1968 season in order to continue or extend work undertaken previously in the Dakotas. One party conducted a shoreline survey, including limited excavation, around the upper reaches of Lake Sharpe-Big Bend Reservoir in South Dakota and a second group completed a third season of work at a prominent village site in south-central North Dakota in the upper Oahe Reservoir.
