Ground-water levels in Wyoming, 1975
Wilbur C. Ballance, Pamela B. Freudenthal
1976, Open-File Report 76-598
Ground-water levels are measured periodically in a network of about 260 observation wells in Wyoming to record changes in ground-water storage. The areas of water-level observation are mostly where ground water is used in large quantities for irrigation or municipal purposes. This report contains maps showing location of observation wells...
The hydrologic setting of lakes in Minnesota and adjacent states; with emphasis on the interaction of lakes and ground water
Thomas C. Winter
1976, Open-File Report 76-81
The hydrologic settings of 150 randomly-selected lakes in the north-central United States were investigated by principal component analysis as a first attempt to develop a general classification of the hydrologic setting of lakes. Precipitation-evaporation balance and the water quality parameters have high factor loadings on the first principal component. Highest...
Landslide problems at West Valley Nuclear Service Center, New York: An assessment and recommendations for study
Robert W. Fleming
1976, Open-File Report 76-661
Problems due to landslides prompted a visit to the West Valley Nuclear Service Center (WVNSC) near Springville, New York, on March 15 and 16, 1976. From this visit a report was prepared and contains the following: An assessment of the landslide conditions. An assessment of the immediacy of the landslide problems. A suggested study program...
Guide to the availability of hydrologic data, Greater Pittsburgh region, Pennsylvania
Robert M. Beall
1976, Open-File Report 76-352
A great variety of hydrologic data are collected by many governmental agencies and other entities for diverse purposes. Some of the data are compiled and reported in readily available, widely known publications; some are not. Continuing requests for information on the locations of data collection sites and on the sources...
Preliminary investigation of faults and folds along the inner edge of the coastal plain in northeastern Virginia
Robert B. Mixon, Wayne L. Newell
1976, Open-File Report 76-330
Four en-echelon northeast-trending structures, including southeast-dipping monoclines and northwest-dipping high-angle reverse-faults, have been mapped along the inner edge of the Coastal Plain in northeastern Virginia -- an area generally considered to be undeformed. Although displacements are small (15to 60 m), the structures markedly affect the present distribution and thickness of...
Geochemical prospecting for Carlin-type gold deposits
Sherman P. Marsh
1976, Open-File Report 76-335
Disseminated, Carlin-type, gold deposits are associated with a volatile suite of elements consisting of Hg, As, Sb, W, and sometimes, but not always, Au. Geochemical exploration for this type of disseminated deposit depends upon recognizing the significance of this volatile suite and interpreting it in light of other geologic and...
Water-quality effects on Baker Lake of recent volcanic activity at Mount Baker, Washington
Gilbert Carl Bortleson, Reed T. Wilson, B. L. Foxworthy
1976, Open-File Report 76-714
Increased volcanic activity on Mount Baker, which began in March 1975, represents the greatest known activity of a Cascade Range volcano since eruptions at Lassen Peak, Calif. during 1914-17. Emissions of dust and increased emanations of steam, other gases, and heat from the Sherman Crater area of the mountain focused...
Report on the environmental geology OCS area, eastern Gulf of Alaska
Bruce F. Molnia, Paul R. Carlson, Terry R. Bruns
1976, Open-File Report 76-206
In anticipation of oil and gas leasing of the outer continental shelf (OCS lease area 39) in the northeastern Gulf of Alaska, the U. S. Geological Survey began a regional reconnaissance in 1974. The study area, which extends from Prince William Sound on the west to Yakutat Bay on the...
