Kansas ground-water observation-well network, 1983
Marilyn E. Pabst
1983, Open-File Report 83-528
The locations of 1,940 selected wells in 72 counties, which comprised the Kansas groundwater observation-well network 1983, are listed. Water level measurements are made in these wells on a continuous, monthly, quarterly, or annual basis. Data collected from the observation well network are stored in a computer and have been...
Groundwater-surfacewater relationships in the Bonaparte Creek basin, Okanogan County, Washington, 1979-1980
F. A. Packard, S. S. Sumioka, K. J. Whiteman
1983, Open-File Report 82-172
Ground water-surface-water relationships were studied in five morphological segments in the Bonaparte Creek basin, Washington during 1979 and 1980. In one segment, kettle lakes were found to be closely associated with the ground-water system. In the other four segments, a close relationship was found between streamflow and ground water. It...
Lake Ellen kimberlite, Michigan, U.S.A.
E. S. McGee, B.C. Hearn
1983, Open-File Report 83-156
The recently discovered Lake Ellen kimberlite, in northern Michigan, indicates that bedrock sources of diamonds found in glacial deposits in the Great Lakes area could lie within the northern U.S. Magnetic surveys show a main kimberlite 200 m in diameter and an adjacent body 25 x 90 m(?). The kimberlite...
Aeromagnetic map of Yucca Mountain and surrounding regions, southwest Nevada
Martin Francis Kane, Robert E. Bracken
1983, Open-File Report 83-616
Magnetic anomalies over Yucca Mountain and surrounding areas are largely caused by variations in magnetic properties and shapes, including structural offsets, of the extensive volcanic units that underlie the region. In a few places the anomalies are caused by intrusions. Correlation between magnetic properties measured from rock samples and those...
Reconnaissance study of stream sedimentation, southern Guam
P.J. Shade
1983, Water-Resources Investigations Report 83-4212
This study uses limited available data to estimate sediment yields for three basins in southern Guam. The flow-duration sediment-rating curve method, reservoir survey data, and Pacific southwest Inter-Agency Committee (PSIAC) formula were used. Daily suspended-sediment samples were collected at USGS gaging stations on the Ylig and Ugum Rivers for one...
Overview and USGS activities
Robert B. McEwen, Hugh W. Calkins
Benjamin S. Ramey, editor(s)
1983, Circular 895-A
The discipline of cartography is undergoing a number of profound changes that center on the emerging influence of digital manipulation and analysis of data. Perhaps the most fundamental distinction between the digital representation of cartographic data and the conventional printed graphic is the need to explicitly and unambiguously code the...
Density, porosity, and magnetic properties of rock specimens from southwestern Arizona
Douglas P. Klein, Gordon R. Johnson
1983, Open-File Report 83-808
Petrophysical data on 364 rock specimens from southwest Arizona are tabulated and summarized by major rock suites for that part of southwest Arizona covered by the Ajo 1? x 2? quadrangle and the Papago Indian Reservation. Data for 202 of these specimens are new and previously unreported. The tabulation also...
Seismicity map of the State of Virginia
B.G. Reagor, C. W. Stover, S. T. Algermissen
1983, Miscellaneous Field Studies Map 1346
The data shown on this map and listed in table 1 are for earthquakes that were originally included in a study of seismic risk in the United States (Algermissen, 1969).  This data file has been recompiled and updated through 1980.  Some revisions of epicenters and intensities in the original file...
