Characteristics of four urbanized basins in south Florida
Robert A. Miller
1979, Open-File Report 79-694
Physical characteristics of four urbanized basins in south Florida are presented. Land use of the four basins are low-density residential, highway, commercial, and high-density residential. Maps of each basin include a photomosaic, a sewerage map, a drainage map, and an impervious-area map. Tabular data include pervious and impervious areas; sewer...
Map showing ground-water conditions in the Virgin River, Grand Wash, and Shivwits areas, Mohave County, Arizona, 1976
G. W. Levings, C. D. Farrar
1979, Water-Resources Investigations Report 79-57
The Virgin River, Grand Wash, and Shivwits areas include about 3 ,250 square miles in northwestern Arizona. Ground water is obtained mainly from the alluvium, conglomerate, and basalt; however, several other formations yield small amounts of water to some wells. In the Virgin River area, most wells are less than...
A supplement to "Methods for collection and analysis of aquatic biological and microbiological samples"
Phillip E. Greeson, editor(s)
1979, Techniques of Water-Resources Investigations 05-A4
The report contains methods used by the U.S. Geological Survey to collect, preserve, and analyze waters to determine their biological and microbiological properties. It supplements, "Methods for Collection and Analysis of Aquatic Biological and Microbiological Samples" (TWRI, Book 5, Chapter A4, 1977, edited by P. E. Greeson, T. A. Ehlke,...
Suspended- and bedload-sediment transport in the Snake and Clearwater rivers in the vicinity of Lewiston, Idaho, August 1976 through July 1978
Michael L. Jones, Harold R. Seitz
1979, Open-File Report 79-417
Impoundment of water in the Snake River and Clearwater River arms behind Lower Granite Dam (see cover map) began in June 1975. At this time, Lower Granite Reservoir and Lock facilities, constructed by the USACE (U.S. Army Corps of Engineers), Walla Walla District, became operational. Construction and operation of this...
The magnetic charts of the United States for Epoch 1975
Eugene B. Fabiano, W. J. Jones, Norman W. Peddie
1979, Circular 810
Approximately 24,000 measurements taken from 1900 to 1974 were analyzed by least-squares methods to produce a series of five magnetic charts of the United States for 1975. A feature of the analysis, differing from techniques used for previous editions of the national chart, is that analytic models define the regional...
Description of dredge samples from the Bering Sea continental margin
Michael S. Marlow, Alan K. Cooper, David W. Scholl, Tracy L. Vallier, Hugh McLean
1979, Open-File Report 79-1139
During 1978 twenty dredge sites were occupied and successfully dredged from the R.V. S.P. LEE along the eastern Bering Sea continental margin (Fig. 1). A total of several tons of rock were collected using a chain-bag dredge. Samples were recovered in water depths ranging from 750 to 2,750 meters from...
Assessment of geothermal resources of the United States: 1978
L.J. Patrick Muffler
1979, Circular 790
The geothermal resource assessment presented in this Circular is a refinement and updating of USGS Circular 726. Nonproprietary information available in June 1978 is used to assess geothermal energy in the ground and, when possible, to evaluate the fraction that might be recovered at the surface. Five categories of geothermal...
Observations on the geology and petroleum potential of the Cold Bay-False Pass area, Alaska Peninsula
Hugh James McLean
1979, Open-File Report 79-1605
Upper Jurassic strata in the Black Hills area consist mainly of fossiliferous, tightly cemented, gently folded sandstone deposited in a shallow marine environment. Upper Cretaceous strata on Sanak Island are strongly deformed and show structural features of broken formations similar to those observed in the Franciscan assemblage of California. Rocks...
Geology, petrology, and chemistry of the Leadville Dolomite: host for uranium at the Pitch Mine, Saguache County, Colorado
J. Thomas Nash
1979, Open-File Report 79-1566
Newly documented uranium ore in the Pitch Mine occurs chiefly in brecciated Mississippian Leadville Dolomite along the Chester reverse fault zone, and to a lesser extent in sandstone, siltstone, and carbonaceous shale of the Pennsylvanian Belden Formation and in Precambrian granitic rocks and schist. Uranium-mineralized zones are generally thicker, more...
Water resources of the southern Powder River area of southeastern Montana
W. Roger Miller
1979, Open-File Report 79-343
The southern Powder River area comprises about 2,230 square miles in southeastern Montana. Sedimentary rocks beneath this area range in age from Cambrian to Holocene and attain a maximum thickness of about 12,000 feet. Rocks exposed in the study area range in age from Late Cretaceous to Holocene.Water for domestic,...
