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.
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 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.
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]
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.
The Wasatch Range (/ ˈ w ɑː s æ tʃ / WAH-satch) or Wasatch Mountains is a mountain range in the western United States that runs about 160 miles (260 km) from the Utah-Idaho border south to central Utah. [1] It is the western edge of the greater Rocky Mountains, and the eastern edge of the Great Basin region. [2]
The extent of internal drainage, the area in which surface water cannot reach the ocean, defines the geographic region called the Great Basin. [7] The Great Basin's internal drainage results from blockage of water movement by high fault-created mountains and by lack of sufficient water flow to merge with larger drainages outside of the Great Basin.
The bottom of the Grand Canyon of the Colorado River in Arizona Great Sand Dunes National Park in Colorado. Together with the Pacific States of Alaska, California, Hawaii, Oregon, and Washington, the Mountain states constitute the broader region of the West, one of the four regions the United States Census Bureau formally recognizes (the Northeast, South, and Midwest being the other three).
