"This report contains data for samples collected during a geochemical survey for uranium in the Cody National Topographic Map Series (NTMS) quadrangle, Wyoming, by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR). [...] Totals of 627 water and 1482 sediment samples were collected from 1529 locations at a nominal density of one location per 10 km2. Water samples were collected from streams, springs, and wells, and sediment samples were collected from streams and springs. Most samples were collected by two private contractors in the summers of 1976 and 1977" (p. 1).

Partial abstract: "During the summers of 1976, 1977, and 1978, 442 water and 1755 sediment samples were collected from 1801 locations within the 19 400 km2 area of the Moab quadrangle, Utah and Colorado, by private contractors for the Los Alamos Scientific Laboratory. Water samples were collected from streams, springs, and wells; wet and dry sediment samples were collected both from stream channels and from springs. Each water sample was analyzed for 13 elements, including uranium, and each sediment sample was analyzed for 43 elements, including uranium, thorium, and vanadium. All field and analytical data are listed in the appendixes of this report" (p. 1).

Preface: This report contains data and information on the resurvey effort and the effect of residual contamination as a result of nuclear weapons development programs conducted in this area.

From foreword: Evaluation of the experimental data on the light isotopes, hydrogen through beryllium, was initiated by LASL in mid-1963. Since the data compilations available were completely inadequate for the task at hand, the tedious program of compiling and plotting was undertaken. As the work progressed an attempt was made to eliminate many of the obvious errors and inconsistencies found in the literature and existing compilations.

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.

As part of the LASL portion of the US EROA NURE program, water samples from 534 locations and sediment samples from 2936 locations were taken over a 7770 square kilometers area of the Estancia Valley in 1975 and analyzed for uranium.

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.

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.

During the spring and summer of 1976, 2144 water and water transported sediment samples were collected from 1685 locations spread over an approximate 21 000 km area of the northern end of the Powder River Basin in northeast Wyoming.
