dition and that a component with pottery like that of the Myers site 

 (vessels with predominantly simple flaring rims and incised decora- 

 tion on both body and rim; rim decoration most often a series of 

 horizontal lines) is present. 



A 2-man survey team detached from this unit spent several days 

 in examination primarily of the east bank of the Missouri River 

 between the Little Bend and Cheyenne Agency. Some sites were 

 revisited and four new archeological locations were recorded in this 

 area, which seems to have a considerably smaller number of sites 

 than most comparable stretches of the river in the Oahe Reservoir 

 area. During one day, two sites in Armstrong County, on the west 

 side of the river, were visited for the first time. 



FIELDWORK IN PALEONTOLOGY 



After an interruption of a year, in 1949, paleontological field inves- 

 tigations were resumed in 1950 and continued in 195 1, under the 

 supervision of Dr. Theodore E. White. With two assistants in 1950 

 and one in 195 1, White revisited six reservoir areas that had previ- 

 ously been examined more or less intensively, initiated work in the 

 three large reservoirs under construction on the Missouri River in the 

 Dakotas, and collected information, through consultation with other 

 paleontologists, relative to the situation in a number of potential res- 

 ervoirs in the Niobrara Basin of northern Nebraska. The 1950 sche- 

 dule included visits to Angostura, Boysen, Anchor, Canyon Ferry, 

 Garrison, Oahe, Fort Randall, and Bonny Reservoirs, in addition to a 

 conference relative to the Niobrara Basin. In 1951, the party returned 

 to the Canyon Ferry, Garrison, Oahe, and Fort Randall Reservoirs 

 and added Tiber Reservoir to its itinerary. 



Two days were spent in the Angostura Reservoir area, during 

 which time a deposit of bones of Pleistocene age reported by the 

 archeologists was examined. No evidence of cultural association was 

 observed and the deposit did not appear to be very productive. At 

 Boysen Reservoir, where in 1948 important collections had been made 

 from the Lower Eocene formations, survey of approximately a week 

 revealed that insufficient weathering had taken place to expose addi- 

 tional materials of significance. It was possible, however, to photo- 

 graph the major structural features of the area. Results were almost 

 wholly negative at Anchor Reservoir, where no vertebrate fossils 

 were found in the exposures of the Permian Embar and the Triassic 

 Dinwoody and Chugwater formations inspected during a stay of four 

 days. A single fragment of sandstone bearing impressions of fish 

 scales found in the bed of an arroyo was the sole specimen observed.
