Archeological Progress Report No. 11, Field Season of 1966

This is the eleventh in a series of annual reports summarizing current field activities within the Missouri River Basin under the auspices of the Inter-Agency Archeological Salvage Program. Twelve field parties, representing one federal and four state agencies, participated in the Missouri Basin program during the summer of 1966. Seven parties were fielded by the River Basin Surveys of the Smithsonian Institution, four of which operated along the mainstem in the Upper Oahe and Big Bend reservoirs in North Dakota and South Dakota. Another Smithsonian party surveyed and excavated sites in the Bowman-Haley and Pipestem reservoirs of North Dakota. Excavation of deep, stratified deposits in a cave in northwestern Wyoming was completed by a joint Smithsonian Institution-National Geographic Society-Whitney Gallery of Western Art (Cody) field party led by a Smithsonian archeologist. The River Basin Surveys also operated two survey parties in areas outside of the Missouri Basin, one in the Garrison Diversion Project of North Dakota and the other in the Saylorville Reservoir of central Iowa.
