The Jackson Mountains are a north-northeast trending mountain range in southwestern Humboldt County , Nevada . The range is flanked on the west by the Black Rock Desert and the Black Rock Range beyond. To the north across the Quinn River and Nevada State Route 140 lie the Bilk Creek Mountains . To the northeast across Kings River Valley is the Double Mountains and to the east are the Sleeping Hills . To the southeast and south lie the Eugene and Kamma Mountains . The ghost town of Sulphur lies just southwest of the pass between the Jackson and Kamma ranges. Nevada State Route 49 ( Jungo Road) and the Union Pacific railroad Feather River Route traverse this pass.
26-488: The range is typical of the Basin and Range Province with isolated high mountains surrounded by downfaulted basins filled with sediments. The rocks of the range include Paleozoic sedimentary and metamorphic rocks intruded by Mesozoic igneous rocks and covered by Mesozoic and Cenozoic volcanic rocks . The highest peak in the range is Quinn Peak , reaching 9,085 ft (2,769 m). Other mountain peaks include: Today
52-522: 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
78-594: A group of related geologic features formed by crustal extension during the Cenozoic era (66.0 million years ago to present). 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
104-417: Is mostly arid and sparsely populated, although there are several major metropolitan areas, such as Reno , Las Vegas , Salt Lake City , Phoenix , Tucson , El Paso — Ciudad Juárez , Mexicali , and Hermosillo . 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
130-477: Is therefore thought to be unrelated to the kind of extension produced by mantle upwelling which may cause narrow rift zones, such as those of the 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
156-884: The Wasatch Fault , the Colorado Plateau and the Rio Grande Rift . The 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
182-427: 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 is approximately 30–35 km and is comparable to extended continental crust around
208-554: The Basin and Range province are controversial, and several competing hypotheses attempt to explain them. 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 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
234-568: 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. 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 crawling northward." The tectonic mechanisms responsible for lithospheric extension in
260-487: 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
286-604: The Jungo Road west for 35 miles to Bottle Creek Road. The Jackson Mountain Range can also be reached by taking the Leonard Creek or Bottle Creek Roads south from State Route 140 . The two wildernesses are divided by Trout Creek Road. The South Jackson area has canyons on the west side of the mountains which provide access for dayhiking and backpacking. McGill, Bliss, and Alaska Canyons are scenic. The eastern slopes of

#1732783265208312-595: The North Jackson Mountains Wilderness. Due to the ruggedness of the area; base camping and dayhiking is recommended. Basin and Range Province 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 physiography of
338-614: The Pacific-Farallon Ridge was subducted beneath 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 Pacific-Farallon Ridge and spawned the San Andreas transform fault , generating an oblique strike-slip component. Today, the Pacific plate moves north-westward relative to North America,
364-532: The South Jackson are gentler in terrain and more suitable for horse travel. Photography, wildlife and wild horse viewing opportunities exists throughout the wilderness area. Hunting for mule deer, California bighorn sheep, antelope and game birds is popular in the area. The North Jackson area provides for camping, dayhiking, photography, wildlife and wild horse viewing opportunities. Deer Creek, Mary Sloan, Happy Creek, and Jackson Creek are scenic streams in
390-416: 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 complexes (MCC), an idea that
416-637: The greater Basin and Range physiographic region. Nor should it be confused with the Basin and Range National Monument , located in Southern Nevada, which is one small part of the much larger province. The Basin and Range Province includes much of western 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
442-684: The majority of the range is divided into two federally protected wilderness area, the North Jackson Mountains Wilderness and the South Jackson Mountains Wilderness . The South Jackson Wilderness offers a panoramic view including the Black Rock Desert , from the top of King Lear Peak at 8,442 feet. Topography of the wilderness is characterized by steep-sided and sharp-crested ridges spotted with juniper and are considered to be
468-891: The most rugged of the Bureau of Land Management 's Winnemucca District. Remnants of the historic Red Butte copper mining district can still be found nearby. The North Jackson Mountains Wilderness' topography is characterized by steep-sided, sharp-crested ridges spotted with juniper, and V-shaped rocky valleys. Elevations in the Wilderness range from 4,000 feet to the high point of Parrot Peak at 8,400 feet. Deep rugged canyons are laden with aspen, willow, and cottonwood groves. Several riparian streams support small populations of introduced rainbow trout. The Jackson Mountains are located in Humboldt County , 56 miles west of Winnemucca, Nevada . Access can be reached from Winnemucca by taking
494-731: The province is White Mountain Peak in California , while the lowest point is the Badwater Basin in Death Valley at −282 feet (−86 m). The province's climate is arid, with numerous ecoregions . Most North American deserts are located within it. The Basin and Range Province should not be confused with the Great Basin , a region defined by its unique hydrological characteristics (internal drainage) that overlaps much of
520-733: The 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 bolson valleys alternating with mountains (as described below). The area
546-742: The province is the result of tectonic extension that began around 17 million years ago in the early Miocene epoch. 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 , and the Sandia Mountains . The highest point fully within

#1732783265208572-595: The province occurred in the Neogene period (23.03-2.58 million years ago) and continues to the present. By the Early Miocene sub-epoch (23.03-15.97 million years ago), much of the Farallon plate had been consumed, and the seafloor spreading ridge that separated the Farallon plate from the Pacific plate ( Pacific-Farallon Ridge ) approached North America. In the Middle Miocene (15.97-11.63 million years ago),
598-424: 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 to 300 km since the onset of extension in
624-420: Was completely consumed and volcanic activity ceased, in part. Olivine basalt from the oceanic ridge erupted around 17 Ma and extension began. In addition to small amounts of Nevada petroleum , the Basin and Range Province supplies nearly all the copper and most of the gold , silver , and barite mined in the United States.

650-455: Was first developed based on studies in this 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
676-566: 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
