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 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 "section" is somewhat larger than the hydrographic definition. The Great Basin culture area, or indigenous peoples of the Great Basin, is a cultural classification of indigenous peoples of the Americas and a cultural region located between the Rocky Mountains and the Sierra Nevada.

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).
The region consists mostly of plateaus and mountain ranges lying between the Rocky Mountains on the east and the Cascade and Sierra Nevada Mountains on the west. It is subdivided into three physiographic provinces : the Columbia Plateau in the north, the Basin and Range Province in the central and southwestern portions, and the Colorado Plateau ...
