SECRETARY'S REPORT 61 



sites to be flooded by the proposed Tiber Keservoir on the Marias 

 River in Montana. Previous surveys in that area had shown three 

 types of sites, consisting of buried occupational levels exposed along 

 the edges of the river terraces, surface sites on the river terraces, and 

 tipi-ring sites on top of the plateau surrounding the reservoir. Be- 

 cause of the nature of the cultures represented, the artifact yield and 

 the work accomplished before the end of the fiscal year was small, 

 but considerable information was being obtained about the sequence 

 of cultures and the general aboriginal characteristics of the area. 



Jack T. Hughes, archeologist, left Lincoln on July 7 and proceeded 

 to the Angostura Reservoir in South Dakota, where he initiated a 

 series of excavations. Hughes continued in charge of that project 

 until September when he resigned from the River Basin Surveys to 

 return to Columbia University for further academic work. Mr. 

 Hughes prepared a report on the results of the Angostura work ob- 

 tained while he was in charge of the field party. 



Donald J. Lehmer, Jr., archeologist, joined the Missouri Basin 

 staff on June 1. He left Lincoln on June 9 with G. Ellis Burcaw and 

 proceeded with him to the Tiber project where he assisted in estab- 

 lishing headquarters. From there he returned to Pierre, S. Dak., 

 and on June 19 began the excavation of a stratified earth-lodge village 

 in the area of the Oahe Dam approach channel. By the end of the 

 fiscal year his party had identified house remains attributable to both 

 the Arikara and the Mandan. 



George Metcalf, field and laboratory assistant, spent the period 

 from July 22, 1949, to November 7, 1949, with the field party at the 

 Angostura Reservoir. During the fall and winter months he assisted 

 in the analysis of the material from the Medicine Creek Reservoir and 

 in the preparation of the report for the excavations made there during 

 the previous fiscal year. He also made a study of ceramic materials 

 from Upper Republican sites which are in the collections of the 

 Nebraska State Historical Society at Lincoln. Metcalf left Lincoln 

 on May 19 with the Wheeler party and at the close of the fiscal year 

 was working at the Angostura Reservoir. 



Robert L. Shalkop joined the staff as an archeologist on June 28, 

 and at the end of the fiscal year was preparing to leave with a recon- 

 naissance party to survey a number of reservoir projects in Montana 

 and Wyoming. 



James M. Shippee, field and laboratory assistant, was a member 

 of the field party at the Angostura Reservoir from early in July until 

 early in November. During the fall and winter months he devoted 

 considerable time to the restoration of pottery vessels and the process- 

 ing of other specimens from the Angostura excavations. During the 

 spring months most of his time was occupied in the preparation of
