Jocelyn A. Peterson, L.M. Martin, L. E. Esparza, Gary J. Cwick
1981, Miscellaneous Field Studies Map 1214-B
In accordance with the provisions of the Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976), the Geological Survey and the Bureau of Mines have conducted mineral surveys on certain areas, which formally had been identified as "natural" and "primitive" areas prior to November 1, 1975.The Wilderness...
Preliminary map showing recently active breaks along the Maacama Fault zone between Hopland and Laytonville, Mendocino County, California
E. H. Pampeyan, Philip W. Harsh, J.M. Coakley
1981, Miscellaneous Field Studies Map 1217
The southernmost 15 km of this map is a product of a study that began in 1975 as part of a study of recency of faulting in coastal California (Ziony and others, 1974; Buchanan-Banks and others, 1978; Pampeyan , 1979). In February 1975, after being shown evidence of recent faulting...
Map showing paleontological control of Paleozoic stratigraphy in New England
Marland P. Billings, Peter T. Lyttle
1981, Miscellaneous Field Studies Map 1302
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology.  Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking.  This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of...
Seismicity map of the state of South Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1325
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Seismicity map of the state of North Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1326
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
X-ray mineralogy of cores from two Guatemalan caldera lakes
Lawrence J. Poppe, Charles K. Paull, Christopher G. Newhall
1981, Open-File Report 81-1333
The U.S. Geological Survey (USGS), under the sponsorship of The Agency for International Development, in cooperation with Dartmouth College, collected 13 cores to study the sedimentation in two Guatemalan cauldera lakes, Atitlan and Ayarza....
Assessment of the Santa Margarita Sandstone as a source of drinking water for the Scotts Valley area, Santa Cruz County, California
K. S. Muir
1981, Water-Resources Investigations Report 81-6
Scotts Valley, Calif., is a rural residential area with a rapidly expanding population. Its mediterranean-type climate yields an average annual rainfall of 40 inches. The Santa Margarita Sandstone is the principal aquifer in the area, supplying about 90 percent of all water for domestic purposes. Sources of recharge for the...
Ground-water hydrology of strip-mine areas in eastern Ohio (conditions during mining of two watersheds in Coshocton and Muskingum counties)
John O. Helgesen, Allan C. Razem
1981, Open-File Report 81-913
Ground-water conditions during coal strip mining in two small watersheds are described as part of an ongoing study of effects of mining on hydrologic systems. Both watersheds were underlain by stratified sedimentary rocks containing two perched aquifers above clay beds which underlaid the major coal seams. Mining involved removing the...
Hydrologic effects of proposed changes in management practices, Winnebago Pool, Wisconsin
William R. Krug
1981, Water-Resources Investigations Report 80-107
Various changes in the management practices for the Winnebago pool have been proposed. The objectives of the proposed changes are protecting wetlands adjacent to the lakes in the pool and assuring adequate flow in the Fox River downstream from Lake Winnebago. Three proposed operation plans for the Winnebago pool were...

William J. Herb, L. C. Shaw, Deborah E. Brown
1981, Open-File Report 81-538
Hydrologic data are presented for area 5 of the Eastern Coal Province, the 7,384 square-mile Monongahela River basin in western Pennsylvania, western Maryland, and north-central West Virginia. One hundred thirty-four streams were sampled about three times during the 1979 and 1980 water years for specific conductance, pH, acidity, alkalinity dissolved...
