Great Basin National Park is located in the southern Snake Range, White Pine County, Nevada, near the ranching community of Baker, Nevada. The Great Basin National Park project began in June 1992 through an interagency agreement between the U.S. Geological Survey (USGS) and the National Park Service (NPS) and was completed in March 1995. The project delivers large-scale geologic maps of the park, a Geographic Information System data base shared between the USGS and NPS, USGS Open-file and Geologic Quadrangle geologic maps, reports on topical studies, and a USGS bulletin on the geologic evolution of the park. The park includes the southern Snake Range, recognized as a metamorphic core complex and exposing the Snake Range decollement, a large-scale, low-angle fault plane surface. Studies are conducted on important regional problems like the age, time of initiation, style, and kinematics of extension in the Basin and Range Geologic Province. Results to date conclude that extension in the Snake Range began from 20 to 15 Ma (million years; early to middle Miocene) earlier than had been previously thought. Products from this project provide data to develop responses to preservation and management issues, to answer requests for public information, and to provide a basis for continued scientific research in the region.
