In situ bulk density and porosity estimates from borehole gravity data in limestones of the Madison Group; test well No. 1, Crook County, Wyoming
Bruce A. Kososki, Stephen L. Robbins
1979, Open-File Report 79-1514
In 1975 the U.S. Geological Survey, in cooperation with the Old West Regional Commission, prepared a plan of study (U.S. Geological Survey, 1975) for evaluating the water-supply potential of limestone of the Madison Group and associated rocks. To obtain better subsurface hydrologic and geologic information it was recognized that Madison...
Streamflow Estimates in Selected Wisconsin Streams
R.P. Novitzki
1979, Open-File Report 79-1282
The Wisconsin Department of natural Resources needs streamflow information in lake basins where lake-rehabilitation programs are implemented but where long-term stream-gaging stations are not justified. The U.S. Geological Survey provided streamflow estimates for 24 streams in Wisconsin. The estimates were made by the use of (1) midmonthly measurements, (2) basin...

Enhancement of Landsat images for lineament analysis in the area of the Salina Basin, New York and Pennsylvania
M. Dennis Krohn
1979, Open-File Report 79-533
Digital image processing of Landsat images of New York and Pennsylvania was undertaken to provide optimum images for lineament analysis in the area of the Salina Basin. Preliminary examination of Landsat images from photographic prints indicated sufficient differences between the spectral bands of the Landsat Multispectral Scanner (MSS) to warrant...
