Uranium Hydrogeochemical and Stream Sediment Reconnaissance in Lincoln and Flathead Counties, Northwest Montana
From abstract: Between mid-May and late June 1976, 3409 water and water-transported sediment samples were collected from 1781 locations spread over an approximate 17 000 kilometer area of northwestern Montana. All of the samples were analyzed for total uranium at the LASL, using standardized procedures and rigorous quality controls--the waters by fluorometry and the sediment (and those waters with >10 parts per billion uranium) by delayed-neutron counting methods.

Multivariate Statistical Analysis of Stream Sediments for Mineral Resources from the Craig NTMS Quadrangle, Colorado
Abstract: Multivariate statistical analyses were carried out on Hydrogeochemical and Stream Sediment Reconnaissance data from the Craig quadrangle, Colorado, to support the National Uranium Resource Evaluation and to evaluate strategic or other important commercial mineral resources. A few areas for favorable uranium mineralization are suggested for parts of the Wyoming Basin, Park Range, and Gore Range. Six potential source rocks for uranium are postulated based on factor score mapping. Vanadium in stream sediments is suggested as a pathfinder for carnotite-type mineralization. A probable northwest trend of lead-zinc-copper mineralization associated with Tertiary intrusions is suggested. A few locations are mapped where copper is associated with cobalt. Concentrations of placer sands containing rare earth elements, probably of commercial value, are indicated for parts of the Sand Wash Basin.

Raw Data Report of Elemental Analyses from Hydrogeochemical and Stream Sediment Samples Taken Near Sterling and Fort Morgan, Northeastern Colorado, December 1976 and January 1977
From summary: The University of Colorado, under contract with the Los Alamos Scientific Laboratory (LASL), is currently performing an evaluation of geochemical relationships of water and sediments and seasonal variations to uranium for the South Platte drainage of northeastern Colorado. As a preliminary part of this study, samples were collected from 125 sites near Sterling and Fort Morgan, Colorado, during the period from December 20, 1976, to January 15, 1977. During this period the weather in the area was clear to partly cloudy, with daytime temperatures ranging from -12 to 12 C. Only a trace of precipitation, in the form of very light snow flurries, occurred during the sampling period. The sample site locations and numbers (the first two digits have been omitted) are shown on Plate I.
Uranium Hydrogeochemical and Stream Sediment Reconnaissance in the San Juan Mountains, Southwest Colorado
From 1995 sites in the San Juan Mountains area, 1706 water and 1982 sediment samples were collected during June-July 1976 and analyzed for uranium. The area includes the southern third of the Colorado mineral belt which has yielded rich ores of gold, silver, copper, lead, zinc, and molybdenum. The broadly domed mountains are capped by 2500 m of Tertiary volcanics, deeply eroded to expose a Precambrian crystalline core. Adjacent plateaus underlain by Mesozoic sedimentary rocks were included in the reconnaissance. Average value of uranium in water samples from mountains was less than 0.5 parts per billion, from plateaus was 1-2 parts per billion, from Mancos shale areas exceeded 2 parts per billion. Anomalous sediment samples, 40 ppm uranium, came from near Storm King Mountain and upper Vallecito Creek. Other anomalous areas, including the Lake City mining district, were well defined by 4-30 parts per million uranium in sediment and 3-30 parts per billion uranium in water. Anomalous areas not previously reported indicate favorable areas for future exploration.

Results of Elemental Analyses of Water and Waterborne Sediment Samples from the Proposed Cape Krusenstern National Monument, Alaska
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.
