The BASIN AND RANGE PROVINCE is a vast physiographic region that covers 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 physiography of the province is the result of tectonic extension that began around 17 Mya (million years ago) in Early Miocene

The numerous ranges within the Province in the United States are collectively referred to as the " Great Basin Ranges", although many are not actually in the Great Basin . Major ranges include the Snake Range , the Panamint Range , the White Mountains , the Sandia Mountains , and the Tetons . Depending on various geographical definitions of the Province, its highest point is either Mount Whitney or Pico de Orizaba , both of which are located at the boundary of the Province and belong to other geologic regions as well. Pico de Orizaba is unambiguously part of the Trans-Mexican Volcanic Belt
Trans-Mexican Volcanic Belt
which has little in common with the Basin and Range Province. The highest point fully within the Province is White Mountain Peak in California
, while the lowest point is the Badwater Basin in Death Valley
Death Valley
at −282 feet (−86 m). The Province's climate is arid, with numerous ecoregions . Most North American deserts are located in the Province.

Clarence Dutton famously compared the many narrow parallel mountain ranges that distinguish the unique topography of the Basin and Range to an "army of caterpillars marching toward Mexico." The Basin and Range province should not be confused with The Great Basin , which is a sub-section of the greater Basin and Range physiographic region defined by its unique hydrological characteristics (internal drainage).

The Basin and Range Province
Basin and Range Province
includes much of western North America
North America
. In the United States, it is bordered on the west by the eastern fault scarp of the Sierra Nevada
and spans over 500 miles (800 km) to its eastern border marked by the Wasatch Fault , the Colorado Plateau and the Rio Grande Rift . The Basin and Range Province
Basin and Range Province
extends north to the Columbia Plateau and south as far as the Trans-Mexican Volcanic Belt in Mexico
, though the southern boundaries of the Basin and Range are debated. In Mexico, the Basin and Range Province

is dominated by and largely synonymous with the Mexican Plateau

Evidence suggests that the less-recognized southern portion of the Basin and Range Province
Basin and Range Province
is bounded on the east by the Laramide Thrust Front of the Sierra Madre Oriental and on the west by the Gulf of California
and Baja Peninsula with notably less faulting apparent in the Sierra Madre Occidental in the center of the southernmost Basin and Range Province.

Common geographic features include numerous endorheic basins , ephemeral lakes, plateaus, and valleys alternating with mountains (as described below). The area is mostly arid and sparsely populated, although there are several major metropolitan areas, including Mexico City , the largest city in the western hemisphere.


It is generally accepted that basin and range topography is the result of extension and thinning of the lithosphere , which is composed of crust and upper mantle . Extensional environments like the Basin and Range are characterized by listric normal faulting , or faults that level out with depth. Opposing normal faults link at depth producing a horst and graben geometry, where horst refers to the upthrown fault block and graben to the down dropped fault block.

The average crustal thickness of the Basin and Range Province
Basin and Range Province
is approximately 30 – 35 km and is comparable to extended continental crust around the world. The crust in conjunction with the upper mantle comprises the lithosphere . The base of the lithosphere beneath the Basin and Range is estimated to be about 60 – 70 km. Opinions vary regarding the total extension of the region; however, the median estimate is about 100% total lateral extension. Total lateral displacement in the Basin and Range varies from 60 – 300 km since the onset of extension in the Early Miocene
with the southern portion of the province representing a greater degree of displacement than the north. Evidence exists to suggest that extension initially began in the southern Basin and Range and propagated north over time.


Snake Range

The tectonic mechanisms responsible for lithospheric extension in the Basin and Range province are controversial, and several competing hypotheses attempt to explain it. Key events preceding Basin and Range extension in the western United States include a long period of compression due to the subduction of the Farallon Plate
Farallon Plate
under the west coast of the North American continental plate which stimulated the thickening of the crust. Most of the pertinent tectonic plate movement associated with the Basin and Range Province
Basin and Range Province
occurred in Neogene time and continues to the present. By Early Miocene
time, much of the Farallon Plate
Farallon Plate
had been consumed, and the seafloor spreading ridge that separated the Farallon Plate
Farallon Plate
from the Pacific Plate (East Pacific Rise ) approached North America. In the Middle Miocene
, the East Pacific Rise was subducted beneath North America
North America
ending subduction along this part of the Pacific margin; however, the Farallon Plate continued to subduct into the mantle . The movement at this boundary divided the East Pacific Rise
East Pacific Rise
and spawned the San Andreas transform fault , generating an oblique strike-slip component. Today, the Pacific Plate moves north-westward relative to North America, a configuration which has given rise to increased shearing along the continental margin .

The tectonic activity responsible for the extension in the Basin and Range is a complex and controversial issue among the geoscience community. The most accepted hypothesis suggests that crustal shearing associated with the San Andreas Fault caused spontaneous extensional faulting similar to that seen in the Great Basin. However, plate movement alone does not account for the high elevation of the Basin and Range region. The western United States is a region of high heat flow which lowers the density of the lithosphere and stimulates isostatic uplift as a consequence. Lithospheric regions characterized by elevated heat flow are weak and extensional deformation can occur over a broad region. Basin and Range extension is therefore thought to be unrelated to the kind of extension produced by mantle upwelling which may cause narrow rift zones, such as the Afar Triple Junction
Afar Triple Junction
. Geologic processes that elevate heat flow are varied, however some researchers suggest that heat generated at a subduction zone is transferred to the overriding plate as subduction proceeds. Fluids along fault zones then transfer heat vertically through the crust. This model has led to increasing interest in geothermal systems in the Basin and Range, and requires consideration of the continued influence of the fully subducted Farallon plate in the extension responsible for the Basin and Range Province.


In some localities in the Basin and Range, metamorphic basement is visible at the surface. Some of these are metamorphic core complex (MCC), an idea that was first developed based on studies in the Basin and Range Province. A metamorphic core complex occurs when lower crust is brought to the surface as a result of extension. MCCs in the Basin and Range were not interpreted as being related to crustal extension until after the 1960s. Since then, similar deformational patterns have been identified in MCCs in the Basin and Range and has led geologists to examine them as a group of related geologic features formed by Cenozoic crustal extension. The study of metamorphic core complexes has provided valuable insight into the extensional processes driving Basin and Range formation.

Prior to the Eocene Epoch (55.8 ±0.2 to 33.9 ±0.1 Ma) the convergence rate of the Farallon and North American Plates was fast, the angle of subduction was shallow, and the slab width was huge. During the Eocene the Farallon Plate

subduction -associated compressive forces of the Laramide , Sevier and Nevada
orogenies ended, plate interactions changed from orthogonal compression to oblique strike-slip , and volcanism in the Basin and Range Province flared up ( Mid-Tertiary ignimbrite flare-up ). It is suggested that this plate continued to be underthrust until about 19 Ma, at which time it was completely consumed and volcanic activity ceased, in part. Olivine basalt
