and the reservoir manager of the Gavins Point Dam. The Laboratory 

 of Anthropology provided a part of the field expenses. This is another 

 example of the outstandingly fine cooperation between various Federal 

 and State agencies in the Inter- Agency Archeological Salvage Pro- 

 gram. The Miller Creek site, on the right bank of Miller Creek at its 

 confluence with the Missouri Eiver in Knox County, Nebraska, is a 

 prehistoric Indian campsite exposed at a depth of from 3 to 6 feet 

 below the surface. Test trenches revealed a moderate quantity of arti- 

 facts including chopping tools, projectile points with and mthout side 

 notches, and a few potteiy fragments. The material relates the site to 

 the Woodland cultures. In addition, a day was spent at a site on the 

 South Dakota side of Lewis and Clark Lake, collecting some deeply 

 buried bison bones that appear to be of an extinct species. 



The 1960 summer field season in the Missouri Basin began in the Big 

 Bend Keservoir area on June 8. Dr. Warren W. Caldwell and the 

 party under his direction, prevented by heavy rains and unexpected 

 high water from reaching its primary objective of sites in Old Arm- 

 strong County, Oahe Reservoir, temporarily transferred their activ- 

 ities for the early part of the season to the area about the mouth of 

 Medicine Creek in Lyman County, South Dakota. By the end of the 

 fiscal year Caldwell had a crew of eight men, and excavations were well 

 underway at Sites 39LM222 and 39LM224, two small earth-lodge vil- 

 lages briefly tested in the 1959 season. 



The second Missouri Basin Project field party starting work in June 

 was under the direction of Eobert W. Neuman. It was engaged in the 

 excavation of a burial-mound site near the North Dakota-South 

 Dakota State line, in the Oahe Reservoir area, Sioux County, North 

 Dakota. This site, the Boundary Mound group (32SI1), consists of 

 several burial mounds of the Plains Woodland period, and is one of 

 the extensive series of Woodland mound sites in the Oahe Reservoir 

 area scheduled for excavation by this party during the 1960 season. 

 By the end of the year excavations at this site were nearly completed. 

 Mr. Neimian and his crew of six men had cut extensive trenches across 

 three of the mounds and had dug several test pits in other parts of the 

 site. 



The third Missouri Basin Project field party at work in June was 

 a crew of three under the direction of G. Hubert Smith in the Oahe 

 Reservoir area. This historic-sites party planned to begin digging on 

 June 23 at the site of old Fort Bennett (39ST26) in Stanley County, 

 South Dakota. When it reached that location, however, it found most 

 of it already under water and a change was necessary. The party 

 moved to Fort Sully (39SL45) in Sully County on the other side of 

 the Missouri River, and on elune 28 started an investigation of the 

 foundations and refuse dumps at that historic military post in order to
