SECRETARY'S REPORT 97 



shoreline survey of Fort Peck Reservoir of east-central Montana, 

 locating archeological sites exposed by slioreluie erosion. Robert Gant 

 of the W. H. Over Museum, University of South Dakota, surveyed 

 the shoreline of Lewis and Clark Lake (the former Gavins Point 

 Reservoir). Dr. Preston Holder, assisted by James Marshall with 

 a crew of students from the University of Nebraska, began salvage 

 excavations in the Glen Elder Reservoir of northwestern Kansas. 

 Several University of Missouri field parties, directed by Dr. Carl 

 H. Chapman, excavated in the Kaysinger Bluff, Stockton, and Mera- 

 mec Basin Reservoirs of Missouri. Each of these field parties oper- 

 ated under agreements with the National Park Service and the Smith- 

 sonian Institution in the Inter- Agency Salvage Program. 



The 1964 field season began with two small survey teams exam- 

 ining sites in the upper Big Bend Reservoir. During the winter of 

 1964 the Missouri Basin Project staff had become aware that the wat- 

 ers behind the Big Bend Dam were rising faster than had been antici- 

 pated. Under the circumstances it was impossible to plan fieldwork 

 for the approaching summer season without a close check on the 

 changing conditions. On April 6 and 7, Richard E. Jensen and 

 Oscar L. Mallory of the Project staff visited archeological sites along 

 the left bank of the reservoir between Chapelle Creek and the city 

 of Pierre. Severe weather conditions made it impossible to examine 

 other areas, but as of that time water damage did not appear to be 

 extensive. The reservoir level had reached a pomt just below many 

 sites, and at least one, 39HU60 at Chapelle Creek, was then an island. 

 Another reconnaissaAce was made by Jensen and Lionel A. Brown 

 on May 7 and 8, but despite a slight interim rise of water level, the 

 archeological situation had not changed significantly. 



On June 9, a group of seven men directed by Wilfred M. Husted, 

 began work in the Yellowtail Reservoir of Montana and Wyoming. 

 This is the third and last season of excavation within the reservoir 

 area. Previously, Smithsonian Institution field parties had concen- 

 trated in the lower and central parts of the reservoir. This year 

 excavations are restricted to the upper Big Horn Canyon, thus com- 

 pleting the investigation of major sites within the reservoir. At the 

 end of the fiscal year the crew was surveying within the upper 

 reservoir. 



On June 10 three additional field parties began work within the Big 

 Bend Reservoir of central South Dakota. The first, a group of nine 

 men directed by Richard E. Jensen, was carrying out large-scale test- 

 ing at the Sommers site (39ST56) on the right bank of the Missouri 

 adjacent to the La Roche sites. It is one of the most significant villages 

 of the Middle INIissouri Tradition surviving within the reservoir. The 

 village contains at least 70 house depressions and has a particularly
