torical Society of North Dakota, the University of South Dakota and 

 the South Dakota Archaeological Commission, the University of 

 Kansas, and three Nebraska agencies — the Nebraska State Historical 

 Society, the University of Nebraska State Museum, and the Labo- 

 ratory of Anthropology of the University of Nebraska — all partici- 

 pated in the salvage program under memoranda of agreement. The 

 University of Kansas in 1950 and 195 1 and the Nebraska State His- 

 torical Society in 195 1 undertook the salvage of sites in the Fort Ran- 

 dall Reservoir, South Dakota, and Montana State University agreed 

 to excavate sites in the Garrison Reservoir, North Dakota, in 1951. 

 In addition, the University of Denver investigated a site in the Bonny 

 Reservoir area, Colorado, in 1950, with its own resources. 



For the summaries that follow I have utilized periodic progress 

 reports and more detailed reports, published or unpublished, when 

 available. It should be pointed out that many of these reports are not 

 the final statements of the archeologists and that undoubtedly in some 

 instances their interpretations will be altered before their final pub- 

 lished reports appear. 



COLORADO 



During a brief survey of the Bonny Reservoir area, Yuma County, 

 in the spring of 1947, a River Basin Surveys party recorded a site 

 from which points variously described as reminiscent of Plainview 

 or of Yuma forms had reportedly been recovered. The site, 5YM7, 

 consists of a "mound" on the side of a small northern tributary of the 

 South Fork Republican River. Only a few flakes and quantities of 

 bison bone, some burned, were observed by the survey party at the 

 site, but points reported to have been found there by a resident of 

 Burlington, Colo., were examined. The site had been called to the 

 attention of Arnold M. Withers, Department of Anthropology, Uni- 

 versity of Denver, and in May 1951, assisted, among others, by Her- 

 bert Dick and Robert Lister of the University of Colorado, he de- 

 voted a weekend to trenching it. The "mound" (which was a natural 

 feature) proved to have been largely destroyed by previous digging, 

 but portions of the thin occupational deposit which were apparently 

 undisturbed were still available for examination. The only inclusions 

 found were innumerable bones and fragments of bone, burned and 

 unburned, some of which occurred in the top few inches of the under- 

 lying basal remnant of an old soil. The bones, some of which are 

 mineralized, are probably of bison. Not even a stone chip was found, 

 and it appears that the limited artifact content of the site had been 

 previously removed.
