tions had been made at a number of these projects by Western State 

 College, Gunnison, students under the direction of Dr. C. T. Hurst of 

 that institution. Working in conjunction with Dr. Hurst and under 

 his general direction, Eastman and Yundt completed the surveys of 

 the Cottonwood, Cebolla, Gateview, and Almont reservoir areas and 

 at the close of the year were engaged in a reconnaissance of the Taylor 

 Lake project. The four basins where investigations were completed 

 contained 16 sites consisting of both rock shelters and open camps. 

 None appeared to be of sufficient importance to warrant recommenda- 

 tion for further study by the Kiver Basin Surveys. However, Dr. 

 Hurst and Western State College volunteered to take over such of 

 the units as indicated the possibility of contributing some knowledge 

 and assume responsibility for the additional work needed to obtain it. 



Arnold M. Withers was appointed to the Surveys staff on June 13 as 

 archeologist and on June 21 left Denver accompanied by W. W. 

 Thompson and M. F. Sullivan, student assistants, to begin the recon- 

 naissance of a number of reservoir projects in the mountains west of 

 Pueblo. This work was going ahead at the close of the fiscal year. 

 Mr. Withers and his associates used space made available by the De- 

 partment of Anthropology of the University of Denver as their base 

 of operations. 



Missouri Basin. — The Missouri Basin project continued in full 

 operation throughout the year. On July 1, three archeological surveys 

 and one paleontological reconnaissance were under way and the head- 

 quarters and laboratory at Lincoln, Nebr., were actively engaged in 

 processing data and specimens received from the field parties. Most 

 of the activities were of a survey nature, but some digging was done 

 at Birdshead Cave in the Boysen Reservoir, Wyo., at Medicine Creek 

 Reservoir, Nebr., and at several paleontological sites in Wyoming. 

 By the end of the first week in November weather conditions were such 

 that it was necessary to stop explorations for the season and all regular 

 personnel returned to Lincoln. From then until conditions again 

 became favorable in the spring, the time was devoted to the study of 

 materials and data collected and the preparation of reports. Field 

 work was initiated March 29, 1948, when an extensive series of exca- 

 vations was started at sites soon to be destroyed by construction oper- 

 ations at the Medicine Creek Dam in western Nebraska. This work 

 was in accordance with an agreement with the Bureau of Reclamation 

 whereby the River Basin Surveys provided the technical supervision 

 and the Bureau of Reclamation furnished the necessary labor and 

 equipment. This undertaking was still in progress at the end of the 

 fiscal year. On June 1 one archeological party left Lincoln for the 

 Angostura Reservoir, S. Dak., for further survey and excavation, and 

 on June 3 another left for Heart Butte Reservoir, N. Dak., to begin 

 similar activities. A paleontological party departed on June 1 for the
