The Basin and Range Province is a vast physiographic region covering much of the inland Western United States and northwestern Mexico. It is defined by unique basin and range topography , characterized by abrupt changes in elevation, alternating between narrow faulted mountain chains and flat arid valleys or basins.
Basin and range topography has alternating parallel mountain ranges and valleys Basin and range topography is characterized by alternating parallel mountain ranges and valleys. It is a result of crustal extension due to mantle upwelling , gravitational collapse, crustal thickening, or relaxation of confining stresses.
The Basin and Range region is the product of geological forces stretching the Earth's crust, creating many north–south trending mountain ranges. These ranges are separated by flat valleys or basins.
Basin and Range National Monument, Nevada. The Basin and Range National Monument area has geological, ecological, cultural, historical, paleoecological, seismological, archaeological, and paleoclimatological significance. [1] The area is located in a transitional region between the Mojave Desert and the Sagebrush Steppe of the Great Basin. [1]
Whatever the cause, the result has been the formation of a large and still-growing region of relatively thin crust; the region grew an average of 1 inch (2.5 cm) per year initially and then slowed to 0.3 inches (0.76 cm) per year in the last 5 million years. [17] Geologists call this region the Basin and Range Province.

The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range.The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey.
Elevation varies from 4,000 to 7,300 feet (1,219 to 2,225 m). The region is less wooded, lower, and more arid than neighboring subregions in the Northern Basin and Range. It differs from sagebrush-dominated regions in the Central Basin and Range in having higher precipitation and colder winters.
