12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I07 



specimens collected will be divided after they have been studied, with 

 representative collections of type specimens deposited in the United 

 States National Museum ; another type series will be placed in Recrea- 

 tion Area exhibits where such are established ; and the remaining 

 materials will be deposited in various functioning State and local in- 

 stitutions. The basic records of the work will be permanently filed at 

 the Smithsonian Institution, and the completed scientific reports will 

 be published in one of the regular Smithsonian publication series. 



Actual field work by the Survey began on August 3, 1946, with 

 preliminary investigations at 28 top-priority Bureau of Reclamation 

 projects and 6 Corps of Engineers units. Inadequate transportation 

 facilities combined with the lateness of the season and consequent 

 need for prompt departure restricted the size of the three survey par- 

 ties to two men each. In each reservoir visited, project engineers, 

 surveyors, and other personnel were consulted, and the area was then 

 searched as thoroughly as the available time permitted. Because the 

 work was done so late in the summer, maturing crops and grass cover 

 made surface-collecting and the delineation of sites particularly dif- 

 ficult. It is expected that more leisurely surveys, made at a more 

 favorable time of the year, will disclose a great many additional sites. 

 The work of this initial reconnaissance, it should be noted, was very 

 greatly expedited by splendid cooperation from Reclamation and En- 

 gineers project personnel, National Park Service, State universities, 

 historical societies, the United States Geological Survey, the Fish 

 and Wildlife Service, and other interested agencies and individuals 

 throughout the Basin. 



Projects visited in the preliminary reconnaissance included Kanop- 

 olis. Cedar Bluff, and Kirwin, in Kansas ; Harlan County, Medicine 

 Creek, Enders, and Box Butte, in Nebraska ; Wray and Cherry Creek, 

 in Colorado ; Glendo, Kortes, Lake Solitude, Boysen, Anchor, and 

 Oregon Basin, in Wyoming; Yellowtail, Canyon Ferry, Tiber, and 

 Medicine Lake, in Montana; Angostura, Deerfield, Blue Horse, 

 Shadehill, and Fort Randall damsite, in South Dakota; and Heart 

 Butte, Dickinson, Broncho, Jamestown, Devils Lake, Sheyenne, 

 Crosby, and Garrison damsite, in North Dakota. In addition, the 

 writer, incidental to other tasks, briefly inspected several important 

 sites at the proposed Oahe damsite, others at old Fort Bennett, and 

 one above Mobridge, all in South Dakota. Some understanding of 

 the vastness of the area under investigation may be gotten from the 

 fact that more than 13,000 miles of motor travel were involved in 

 this preliminary work. Missouri, where several large Corps of En- 

 gineers projects are pending, was not visited in 1946.
