This dataset includes the magnetotelluric (MT) sounding data collected in 2003 along a north-south profile west of Wendover, Nevada. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It is also important to know the location and orientation of the Archean/Proterozoic suture zone between these provinces as well as major basement structures within these terranes because they may influence subsequent patterns of sedimentation, deformation, magmatism, and hydrothermal activity. This study was funded by the U.S....
This dataset contains photographs keyed to station points along the Blue Ridge Parkway in Virginia. Photographs are titled and arranged by 7.5-minute quadrangle, and station points are located in the "Detailed geologic mapping geodatabase for the Blue Ridge Parkway in Virginia." The first part of the photograph's filename corresponds to the FieldID attribute of the PhotoPoints entity in the Blue Ridge Parkway Geodatabase. The photographs in this collection are for the Snowden quadrangle, but are also part of a larger data release (Carter et al., 2016). For Snowden, there are 54 jpg in the collection.

Development of oil and gas wells leads to the destruction and fragmentation of natural habitat. Oil and gas wells also increase noise levels which has been shown to be detrimental to some wildlife species. Therefore, the density of oil and gas wells in the western United States was modeled based on data obtained from the National Oil and Gas Assessment.

This data set depicts soil characteristics in western North America. The data set was created from NRCS STATSGO soil data. Calculations were made to reduce one to many relationships to one to one relationships in order to summarize average water capacity, depth to rock, salinity, and pH for each map unit (MUID). ArcMap 8.3 was used to import .dbf files and merge newly created attribute fields to the GIS soil coverage.

This dataset includes the magnetotelluric (MT) sounding data collected in 2006 in the Southern San Luis Valley, Colorado. The U.S. Geological Survey conducted a series of multidisciplinary studies, including MT surveys, in the San Luis Valley to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift. The shallow unconfined and the deeper confined Santa Fe Group aquifers in the San Luis Basin are the main sources of municipal water for the region. The population of the San Luis Valley region is growing rapidly and water shortfalls could have serious consequences. Future growth and land management...

Investigations of coastal change and coastal resources often require continuous elevation profiles from the seafloor to coastal terrestrial landscapes. Differences in elevation data collection in the terrestrial and marine environments result in separate elevation products that may not share a vertical datum. This data release contains the assimilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S., focused on the coastal interface. All datasets were converted to a consistent horizontal datum, the North American Datum of 1983, but the native vertical datum for...
