From introduction: This report describes work done in the Noatak and portions of the Baird Mountains and Ambler River, Alaska, National Topographic Map Series (NTMS) quadrangles (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

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.

From introduction: The purpose of this report is to make available to the public the results of a hydrogeochemical survey for uranium in the stream and lake waters and sediments of the Susitna River basin, Alaska. This work was done by the Los Alamos Scientific Laboratory (LASL) for the US Energy Research and Development Administration (ERDA) as part of the National Uranium Resource Evaluation (NURE) program.

From abstract: During July-August 1976, water and sediments were collected for the Los Alamos Scientific Laboratory from streams and lakes over an area of -100 000 km2 around Kotzebue, Alaska. The sampling was by helicopter, as part of the NURE Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) sponsored by the US ERDA. It was done according to rigorous, but simple, written procedures, at a nominal density of one location per 23 km 2, and included the 1400- to 1900-km2 area proposed for the Cape Krusenstern National Monument. All the samples would normally have been analyzed for uranium and presented in a regular HSSR report. However, due to an interest in the proposed Monument area, the Anchorage office of the Department of Interior, Bureau of Mines, provided funds for multielement analyses on the sediments taken from there. Consequently, in addition to the routine field data and uranium determinations for waters and/or sediments from 89 locations sampled over the proposed Cape Krusenstern Monument, the results of analyses of 44 additional elements in 77 of the sediments from there are provided. Sample locations are shown on a 1:250 000-scale plate. The data and descriptions of the methods used are in appendices.

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 by the Los Alamos Scientific Laboratory (LASL) for the United States Department of Energy (US DOE) over a 50 000-km2 area on the Seward Peninsula and vicinity, Alaska, in 1976 (Fig. 1). The DOE Grand Junction Office (GJO), in Colorado, is responsible for administering the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) as part of its National Uranium Resource Evaluation (NURE) program.
