The Geologic Story of Colorado National Monument
Stanley William Lohman
1981, Bulletin 1508
From 1946 until about 1956 I carried out fieldwork intermittently on the geology and artesian water supply of the Grand Junction area, Colorado, the results of which have been published. The area mapped geologically contains about 332 square miles in the west-central part of Mesa County and includes all of...
An annotated bibliography of literature on Alaska water birds
Colleen M. Handel, Margaret R. Petersen, Robert E. Gill Jr., Calvin J. Lensink
1981, FWS/OBS 81/12
The demand for information on birds in Alaska has surged within the past few years, primarily because of the need to adequately assess the impacts of a wide range of planned developments. The accompanying increase in studies of avian populations has resulted in a growing need for a comprehensive bibliography...
Geochemical survey of Shining Rock Wilderness, Heywood County, North Carolina
Frank G. Lesure
1981, Miscellaneous Field Studies Map 1290-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Shining Rock Wilderness (fig. 1) to test for unidentified or unexposed mineral deposits that might be recognized by their geochemical halos.  Similar geochemical survey based on trace-element analyses have been credited with the discovery of many types of...
Maps showing mines, quarries, prospects, and exposures in the Cheat Mountain Roadless Area, Randolph County, West Virginia
Paul T. Behum, Richard W. Hammack
1981, Miscellaneous Field Studies Map 1271-C
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. Results must be made available to the public and be submitted to the President...
Map showing geothermal resources of the Lake City-Surprise Valley Known Geothermal Resource Area, Modoc County, California
1981, Miscellaneous Field Studies Map 1299
This report summarizes geothermal data from published and unpublished geophysical, geochemical, and geologic reports on Surprise Valley that have been prepared during the past 26 years.  Particular emphasis is placed on a comprehensive structural interpretation of the west half of the valley that is based on map compilation of concealed...
Water resources data for Texas, water year 1980, Volume 3: Colorado River basin, Lavaca River basin, Guadalupe River basin, Neces River basin, Rio Grande basin, and intervening coastal basins
United States Geological Survey
1981, Water Data Report TX-80-3
Surface-water data for the 1980 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also...
Decentralized shared computers in the National Earthquake Hazards Reduction Program
Peter L. Ward, James Herriot, William F. Jolitz
1981, Open-File Report 81-104
The needs for computer analysis in the National Earthquake Program are varied, complex, and rapidly growing. Major sources of frustration have been the difficulty of keeping up with the required analysis, and the difficulties of sharing a wide variety of data and computer programs among several hundred researchers at dozens...
Hydrologic effects of stress-relief fracturing in an Appalachian Valley
Granville G. Wyrick, James W. Borchers
1981, Water Supply Paper 2177
A hydrologic study at Twin Falls State Park, Wyoming County, West Virginia, was made to determine how fracture systems affect the occurrence and movement of ground water in a typical valley of the Appalachian Plateaus Physiographic Province. Twin Falls was selected because it is generally unaffected by factors that would...
Dissolution of sphalerite in ferric chloride solution
Huai Su
1981, Open-File Report 81-609
The dissolution of sphalerite in acidic ferric chloride solution of polished flat surfaces and of spherical particle surface was investigated. Tests were conducted on sphalerite to study rate of dissolution by the effects of stirring speed, temperature, ferric and ferrous concentrations, purity, and particle size.Kinetic investigations were conducted in a...
Hydrogeologic conditions in the coastal plain of New Jersey
Eric F. Vowinkel, W. Kendall Foster
1981, Open-File Report 81-405
A wedge-shaped mass of unconsolidated sediments composed of alternating layers of clay, silt, sand, and gravel underlies the Coastal Plain of New Jersey. The hydrologic units of this mass vary in thickness, lateral extent, lithology, and water-bearing characteristics. Some of the units act as aquifers, whereas other units act as...
Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1979
C.M. Wood, H.S. Butler, J.D. Benton
1981, Open-File Report 81-491
Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Houston, and San Antonio. The study for the Fort Worth metropolitan area was completed at the end of the 1978 water year, and this report is...
Ground-water data for Georgia, 1980
S.E. Matthews, Willis G. Hester, M. P. O’Byrne
1981, Open-File Report 81-1068
More than 2,000 water-level measurements made in Georgia in 1980 provided the basic data for this report. Daily mean water-level fluctuations and trends are shown in hydrographs for the previous year and fluctuations of the monthly mean water level are shown for the previous 10 years in selected observation wells...
Manual for leveling at gaging stations in North Carolina
N.O. Thomas, N.M. Jackson
1981, Open-File Report 81-1104
This manual was prepared to serve several purposes in the U.S. Geological Survey North Carolina District. This manual sets forth District policy as to frequency of levels, accuracy criteria, procedures for checking the datum and setting of the various types of gages, general rules to follow in establishing the original...
