The purpose of this report, which was prepared in cooperation with the City of Houston, the Harris-Galveston Coastal Subsidence District, and the Texas Department of Water Resources, is to show the altitudes of water levels in wells in the Chicot and Evangeline aquifers in the Houston, Texas, metropolitan area.  The...

The Farah Garan ancient mine is located at fat 17?41'00'' N., long 43?38'15'' E. in the southwestern part of the Kingdom of Saudi Arabia. Three diamond drill holes intersected base-metal sulfides, which are present both as conformable layers in Precambrian tuffaceous volcanic rocks and as fracture fillings, irregularly shaped masses,...

Analysis of data from 60 wells in and around the Nevada Test Site, including 16 in the Yucca Mountain area, indicates a thermal regime characterized by large vertical and lateral gradients in heat flow. Estimates of heat flow indicate considerable variation on both regional and local scales. The variations are...

This study deals with 16 palynological samples from Arizona, New Mexico, and Utah, that represent six members of the Chinle Formation of Late Triassic age. The samples, in ascending sequence, show a gradual change in the spore-bisaccate ratio from a preponderance of spores to numerical dominance of bisaccate pollen grains....

The mineral resource potential of the Gila-San Francisco Wilderness Study Area (AZ-040-022/023/024) is low (fig. 2). Although favorable geologic environments for placer gold deposits and manganese vein deposits are present in the study area, the probability of discovering economically exploitable deposits of these metals is low, and not encouraging. Even...

This map shows surface ruptures associated with the M 6 Mammoth Lakes earthquakes of May 25-27, 1980 (Sherburne, 1980). The ruptures were mapped during USGS field investigations May 28 to June 4 and July 14-19, 1980. The map also includes some of the ruptures recorded by California Division of Mines and Geology...

Water resources data for the 1982 water year for Louisiana consist of records of ' stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report, in two volumes, contains records for water discharge...

The Cohutta Wilderness and the Hemp Top Roadless Area have minor occurrences of metallic minerals, but no known resource potential for such minerals in the forseeable future, judging by available data, and only a very minor potential for stone for aggregate, road construction, and similar nondimension use. The rocks of...

The Lower San Francisco Wilderness Study Area consists of a narrow strip 1-2 mi (2-3 km) wide between the rims of the San Francisco River canyon. The wilderness study area has a moderately high potential for geothermal resources, a low to moderate potential for base metal or precious metal resources...

The james River Face Wilderness comprises 8,800 acres in the Jefferson National Forest and occupies parts of Bedford and Rockbridge Counties, west-central Virginia.  It is about 2 mi southeast of Natural Bridge Station and 0.5 mi south of Glasgow (fig. 1). Access is provided by U.S. Route 501, State Route 130,...

This report is last in a series of 11 map sets depicting geohydrologic conditions in selected aquifers in upstate New York. Geohydrologic data are compiled on five maps at 1:24,000 scale. Together the maps provide a comprehensive overview of a buried glacio-fluvial aquifer in Monroe County. The maps include surficial...

We measured the proximate composition (percentage lipid, water, fat-free dry material, ash) and caloric content of eight species of Lake Michigan fish: lake trout (Salvelinus namaycush), coho salmon (Oncorhynchus kisutch), lake whitefish (Coregonus clupeaformis), bloater (Coregonus hoyi), alewife (Alosa pseudoharengus), rainbow smelt (Osmerus mordax), deepwater sculpin (Myoxocephalus quadricornis), and slimy...

Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild,"...
