Geochemical maps of the Southern Massanutten Roadless Area, Page and Rockingham counties, Virginia
Frank G. Lesure, Carl L. Forn
1985, Miscellaneous Field Studies Map 1527-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Southern Massanutten Roadless Area to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos.  Sixty-two stream-sediment and 52 rock samples were collected from within and near the study area by Lesure, assisted...
Habitat Suitability Index Models: Northern bobwhite
Richard L. Schroeder
1985, FWS/OBS 82/10.104
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the northern bobwhite (Colinus virginianus). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Water Resources Research Grant Program project descriptions, fiscal year 1985
U.S. Geological Survey Branch of Research Grants and Contracts
1985, Open-File Report 85-687
Information on each of the 24 projects funded by the U.S. Geological Survey in FY 1985 under section 105 of Public Law 93-242 (the Water Resources Research Act of 1984) is presented, including the grant number, organization, the period of performance, and a brief description of the work to be...
Delineation and description of the regional aquifers of Tennessee — The Knox Aquifer in central and west Tennessee
J. V. Brahana, M. W. Bradley
1985, Water-Resources Investigations Report 83-4012
The Knox aquifer is composed of the Cambrian and Ordovician age carbonate rocks of the Knox Group. This aquifer occurs throughout Tennessee, west of the Valley and Ridge province. The Knox crops out in the Sequatchie Valley and in the Wells Creeks cryptoexplosive structure on the Northwestern Highland Rim. Groundwater...
Habitat Suitability Index Models and Instream Flow Suitability Curves: Arctic grayling riverine populations
Wayne A. Hubert, Rhonda S. Helzner, Lawrence A. Lee, Patrick C. Nelson
1985, FWS/OBS 82/10.110
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model and instream flow suitability curves for Arctic grayling (Thymallus arcticus) riverine populations. The model consolidates habitat use information into a framework appropriate for field application, and is sclaed to produce an index between...
Evaluation of the ground-water resources of the lower Susquehanna River basin, Pennsylvania and Maryland
James M. Gerhart, George J. Lazorchick
1985, Open-File Report 84-748
Ground water in the 3,458-square-mile lower Susquehanna River basin occupies secondary openings in bedrock. The distribution of openings is a function of lithology, depth, and topography. Local flow systems account for most of the total ground-water flow. Average annual recharge for the lower basin is 1,857 million gallons per day,...
Maps showing water geochemistry of the Buffalo Peaks Wilderness Study Area, Lake, Park, and Chaffee Counties, Colorado
G.A. Nowlan, Walter H. Ficklin, Robert A. Dover
1985, Miscellaneous Field Studies Map 1628-E
This report presents results of geochemical studies carried out in June and July of 1982 in the Buffalo Peaks Wilderness Study Area, Colo. (see index map). Samples of water were collected from 84 streams and 18 springs draining the study area. Tabulations of the analyses and a sample locality map...
Sequentially and alternatively developed heights for two representative bench marks: near Palmdale, California and along the Bill Williams River, Arizona
Thomas D. Gilmore, Michael R. Elliot
1985, Open-File Report 85-399
This report consists chiefly of 41 tables that both describe and fully document the reconstructions of a series of alternately developed heights based on levelings leading into two representative bench marks in the southwestern United States. One of these marks, 3219, Vincent, California (fig. 1), lies within the area of...
Maps showing distribution of bismuth in heavy-mineral concentrates, Richfield 1 degree by 2 degrees Quadrangle, Utah
William R. Miller, Jerry M. Motooka, John B. McHugh
1985, Miscellaneous Field Studies Map 1246-E
These maps are part of a folio of maps of the Richfield 1o x 2o quadrangle, Utach, prepared under the Conterminous United States Mineral Assessment Program. Other publications in this folio are listed in the selected references.  Located in west-central Utach, the Richfield quadrangle covers the eastern part of the Plioche-Marysvale ingeous...
Progress report on Black Mesa monitoring program, 1984
G. W. Hill
1985, Open-File Report 85-483
The N aquifer is an important source of water in the 5,400 square-mile Black Mesa area on the Navajo and Hopi Indian Reservations. The project is designed to monitor long-term effects on the ground-water resources of the mesa as a result of withdrawals from the aquifer by a strip-mining operation....
