Effects of coal mine subsidence in the western Powder River basin, Wyoming
C. Richard Dunrud, Frank W. Osterwald
1978, Open-File Report 78-473
Analyses of the surface effects of past underground coal mining in the western Powder River Basin suggest that underground mining of strippable coal deposits will damage the environment more over long periods of time than will modern surface mining, provided proper restoration procedures are followed after surface mining. Subsidence depressions...

Gravity survey of the Tularosa Valley and adjacent areas, New Mexico
D.L. Healey, R. R. Wahl, F. E. Currey
1978, Open-File Report 78-309
The gravity survey of the Tularosa Valley and adjacent areas is a compilation of gravity data acquired from several sources and reduced to the 1971 International Gravity Standardization Network datum. In addition, three local surveys were made that helped to fill in gaps in the gravity coverage. The resulting complete...
Landsat investigations of the northern Paradox basin, Utah and Colorado: Implications for radioactive waste emplacement Part 1. Lineaments and alignments
Jules D. Friedman, Shirley L. Simpson
1978, Open-File Report 78-900
The first stages of a remote-sensing project on the Paradox basin, part of the USGS (U.S. Geological Survey) radioactive waste-emplacement program, consisted of a review and selection of the best available satellite scanner images to use in geomorphologic and tectonic investigations of the region. High-quality Landsat images in several spectral...
A lithologic log of the Oak Grove core, northeastern Virginia
James R. Estabrook, Juergen Reinhardt
1978, Open-File Report 78-855
The Oak Grove core was taken as part of a multifaceted project to develop a stratigraphic and tectonic framework for the Rappahannock drainage basin, northeastern Virginia. This core is at present the only continuously cored Cretaceous and Tertiary section on the Northern Neck of Virginia and is one of the...
