Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Map showing structure contours on the top of the upper Jurassic Morrison Formation, Powder River basin, Wyoming and Montana Map showing structure contours on the top of the upper Jurassic Morrison Formation, Powder River basin, Wyoming and Montana
This map is one in a series of U.S. Geological Survey Miscellaneous Field Studies (MF) maps showing computer-generated structure contours, isopachs, and cross sections of selected formations in the Powder River basin, Wyoming and Montana. The map and cross sections were constructed from information stored in a U.S. Geological Survey Evolution of Sedimentary Basins data base. This data...
Map showing the association of linear features with metallic mines and prospects in the Butte 1° x 2° quadrangle, Montana Map showing the association of linear features with metallic mines and prospects in the Butte 1° x 2° quadrangle, Montana
This study was undertaken as part of the Conterminous U.S. Mineral Assessment Program (CUSMAP). The purpose of the study was to map linear features on Landsat Multispectral Scanner (MSS) images and a proprietary side-looking airborne radar (SLAR) image mosaic and to determine the spatial relationship between these linear features and the locations of metallic mineral occurrE-nces. The...
Maps showing hydrostatic levels and general ground-water quality for an area near Conifer, Colorado Maps showing hydrostatic levels and general ground-water quality for an area near Conifer, Colorado
Static water levels (SWL's) were measured in more than one hundred wells in the study area during April-May 1989. The water levels were monitored for 10-15 minutes to determine if they were static. If a given level was found not to be static, the measurement was repeated at a later data when the level was static.
