A report regarding a survey of the condition of wells and springs in the Rio Blanco County, in N.W. Colorado.

From introduction: This folio was compiled to facilitate the use of groundwater as a sampling medium to aid in exploration for hitherto undiscovered deposits of uranium in the subsurface rocks of Minnesota. The report consists of the following sheets of the hydrogeologic map of Minnesota: 1) map of bedrock hydrogeology, 2) generalized cross sections of the hydrogeologic map of Minnesota, showing both Quaternary deposits and bedrock, 3) map of waterwells that penetrate Precambrian rocks in Minnesota. A list of these wells, showing locations, names of owners, type of Precambrian aquifers penetrated, lithologic material of the aquifers, and well depths is provided in the appendix to this report.

From summary: The procedure has been to search for areas in which nonpedogenic calcrete or gypcrete may have developed and where additional study or exploration might be justified.

Various flow visualization results at a nominal Mach number of 5 are presented for cylindrically blunted, unswept and 60-degree swept fins with and without small clearance gaps, partially immersed in a turbulent boundary layer of about 2.6 inches thickness. In addition, pressure and heat transfer measurements were obtained on the flat plate upon which the fin was mounted. Oil smear, azobenzene and Schlieren flow visualization tests were made.

From introduction: This study considered the region comprising the Upper Mississippi and Lower Missouri River basins and to assess the contributions to the radiation potentially received by the populace from airborne radionuclides originating in adjacent areas, an "air envelope" zone, some 200 miles wide.

From abstract: This report presents preliminary results of stream sediment and ground water reconnaissance in the Charlotte National Topographic Map Series (NTMS) 1° x 2° quadrangle. Stream sediment samples were collected from small streams at 1254 sites for a nominal density of one site per 13 square kilometers (five square miles) in rural areas. Ground water samples were collected at 759 sites for nominal density of one site per 25 square kilometers (ten square miles).

Supplementary table with data on areal distribution of stream water conductivity values to accompany a report on stream sediment and ground water in the Charlotte National Topographic Series (NTMS) 1° x 2° quadrangle.

From summary: Granitic and contact-metamorphic rocks of the Owens Valley area were sampled to determine their favorability for uranium. Uranium deposits associated with these rocks were examined to determine the mode of occurrence.

Supplementary data containing geologic, location, and radiometric maps of Owens Valley area, Inyo and Mono Counties, California, and Esmeralda and Mineral Counties, Nevada.

From summary: A preliminary geologic investigation was conducted to determine if the Triassic sedimentary rocks of the Sanford basin and Colon cross structure in North Carolina are favorable hosts for uranium deposits. Rocks of the adjacent Carolina slate belt were also examined as a potential source of uranium

Supplementary data containing a geologic cross section of the Triassic Sanford Basin to accompany a report on U.S. uranium resources in North Carolina.

From introduction: This report presents the results of a preliminary study of the uranium favorability of lower and middle Eocene rocks in the Wilcox and Claiborne Groups in the Texas Gulf Coastal Plain. The project began October 1, 1976, and was completed March 1, 1977, by personnel of Bendix Field Engineering Corporation (BFEC) under the auspices of the U.S. Energy Research and Development Administration (ERDA).

Supplementary data containing geologic maps and analysis reports of the Wilcox and Claiborne Groups to accompany a report on uranium favorability in Texas.

"CER Geonuclear has developed, in cooperation with the Atomic Energy Commission, a set of detailed plans utilizing nuclear explosives for an underground engineering experiment called project Rio Blanco. The overall objective is to prove the commercial feasibility of using nuclear explosives to recover commercial quantities of tightly held natural gas in the Piceance Basin."

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.

This is the second part of a report of a uranium hydrogeochemical and stream sediment pilot survey of areas of New Mexico.

From introduction: This report describes work done in the Durango National Topographic Map Series (NTMS) quadrangle, Colorado, by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).
