The Buckeystown quadrangle is underlain mostly by rocks of the western Piedmont province and a portion of the eastern Blue Ridge province. The western Piedmont province is underlain by Late Proterozoic(?) and Lower Cambrian(?) metasedimentary rocks of the Westminster terrane, Lower and Middle Cambrian metasedimentary rocks and Upper Cambrian to...
Topographic map of the Parana Valles region of Mars MTM 500k -25/337E OMKT
Water Resources Division, U.S. Geological Survey
2003, IMAP 2787
This map, compiled photogrammetrically from Viking Orbiter stereo image pairs, is part of a series of topographic maps of areas of special scientific interest on Mars. MTM 500k –25/347E OMKT: Abbreviation for Mars Transverse Mercator; 1:500,000 series; center of sheet latitude 25° S., longitude 347.5° E. in planetocentric coordinate system...
Topographic map of the Southeast Loire Valles region of Mars MTM 500k -20/347E OMKT
Water Resources Division, U.S. Geological Survey
2003, IMAP 2786
This map, compiled photogrammetrically from Viking Orbiter stereo image pairs, is part of a series of topographic maps of areas of special scientific interest on Mars. MTM 500k –20/347E OMKT: Abbreviation for Mars Transverse Mercator; 1:500,000 series; center of sheet latitude 20° S., longitude 347.5° E. in planetocentric coordinate system...
Simulation of ground-water flow and land subsidence in the Antelope Valley ground-water basin, California
David A. Leighton, Steven P. Phillips
2003, Water-Resources Investigations Report 2003-4016
Antelope Valley, California, is a topographically closed basin in the western part of the Mojave Desert, about 50 miles northeast of Los Angeles. The Antelope Valley ground-water basin is about 940 square miles and is separated from the northern part of Antelope Valley by faults and low-lying hills. Prior to...
Ferricrete, manganocrete, and bog iron occurrences with selected sedge bogs and active iron bogs and springs in the upper Animas River watershed, San Juan County, Colorado
Douglas B. Yager, Stan E. Church, Philip L. Verplanck, Laurie Wirt
2003, Miscellaneous Field Studies Map 2406
During 1996 to 2000, the Bureau of Land Management, National Park Service, Environmental Protection Agency, United States Department of Agriculture (USDA) Forest Service, and the U.S. Geological Survey (USGS) developed a coordinated...
Suspended-sediment concentration and pool sedimentation data for the Gibbon River, Yellowstone National Park, Wyoming, September 2000 through October 2001
Peter R. Wright, Ronald B. Zelt
2003, Open-File Report 2003-185
This report presents data on streamflow, suspended-sediment concentration, geomorphic measurements of pools, and particle-size distribution of surficial bed material, collected along a 5-mile reach of the Gibbon River in Yellowstone National Park. The study was done in cooperation with the National Park Service. The Park Service was concerned about the...
Hydrology and water quality of an urban stream reach in the Great Basin — Little Cottonwood Creek near Salt Lake City, Utah, water years 1999–2000
Steven J. Gerner, Kidd M. Waddell
2003, Water-Resources Investigations Report 2002-4276
The hydrology and water quality of an urbanized reach of Little Cottonwood Creek near Salt Lake City, Utah, were examined as part of the Great Salt Lake Basins study, part of the U.S. Geological Survey National Water-Quality Assessment program. Physical and chemical properties of the stream were referenced to established...
Estimating spatial variability of recharge in southern New Jersey from unsaturated-zone measurements
Arthur L. Baehr, Leon J. Kauffman, Kimberlie Perkins, Bernard T. Nolan
2003, Water-Resources Investigations Report 2002-4288
Spatial variability of recharge in southern New Jersey was studied by sampling the unsat-urated zone at 48 sites distributed over approximately 930 square kilometers. Samples of unsaturated-zone sediment were collected during the summer and fall of 1996. Unsaturated flow was calculated using moisture-content data and estimates of conductivity and matric...
Descriptions of mineral occurrences and interpretation of mineralized rock geochemical data in the Stikine geophysical survey area, Southeastern Alaska
Cliff D. Taylor
2003, Open-File Report 2003-154
Detailed descriptions of some of the more significant mineral occurrences in the Stikine Airborne Geophysical Survey Project Area are presented based upon site-specific examinations by the U.S. Geological Survey in May of 1998. Reconnaissance geochemical data on unmineralized igneous and sedimentary host rocks, and mineralized rocks are also presented and...
Four models used for numerical simulation of a borehole radar antenna
Karl J. Ellefsen, David L. Wright
2003, Open-File Report 2003-155
In this report are four different models that represent an antenna used by personnel at the U.S. Geological Survey for crosswell investigations. The four models vary in complexity and concomitantly the accuracy with which they represent the actual antenna. These models are used in numerical simulations of the antenna to...
Use of multispectral Ikonos imagery for discriminating between conventional and conservation agricultural tillage practices
Andres Vina, Albert J. Peters, Lei Ji
2003, Photogrammetric Engineering and Remote Sensing (69) 537-544
There is a global concern about the increase in atmospheric concentrations of greenhouse gases. One method being discussed to encourage greenhouse gas mitigation efforts is based on a trading system whereby carbon emitters can buy effective mitigation efforts from farmers implementing conservation tillage practices. These practices sequester carbon from the...
