From abstract: During the summer of 1977, 1268 water and 1206 sediment samples were collected from 1292 lakes and streams throughout the 33 600-km2 area within the boundaries of the McGrath and Talkeetna National Topographic Map Series quadrangles in south-central Alaska. Each of the water samples was analyzed for uranium and 12 other elements, and each of the sediment samples was analyzed for uranium, thorium, and 41 other elements. All of the field and analytical data are listed in appendixes to this report, but only the uranium and thorium data are discussed herein.
During the summer of 1975, the Alaska Division of Geological and Geophysical Surveys (DGGS) conducted a 6-week reconnaissance in widespread areas of Alaska as part of the National Uranium Resource Evaluation (NURE) program sponsored by the Department of Energy (DOE). Water, stream sediment, and bedrock samples were taken from the eastern Seward Peninsula, from north of Koyukuk River, from the Charley River area, and from across south-central Alaska, to aid in determining the uranium potential of the state.
From introduction: This report describes work done in the Rawlins, Wyoming, National Topographic Map Series (NTMS) quadrangle (US Geological Survey, 1968) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).
