Nevada Basin

Last updated

The Nevada Basin [1] is the Great Basin area surrounded by river basins and, to the east, the Great Salt Lake basin (Pleistocene Lake Bonneville basin). The bounding river basins include those of the following (clockwise from south-southeast): Sevier River, Muddy River (Meadow Valley Wash, White River), Las Vegas Wash, Colorado River, Mojave River, Amargosa River, Owens River, Lake Lahontan basin (Walker River, Carson River, Humboldt River, Reese River), and Snake River. [1] The 1850 diagonal California state lines with the Utah Territory & New Mexico Territory are along the general direction of the Nevada Basin's southwest drainage divide (rim), while the north-to-south rim on the east is through the area of the three meridians (1861, 1862, & current 1864) used for the Nevada-Utah state line.

Great Basin large depression in western North America

The Great Basin is the largest area of contiguous endorheic watersheds in North America. It spans nearly all of Nevada, much of Oregon and Utah, and portions of California, Idaho, and Wyoming. It is noted for both its arid climate and the basin and range topography that varies from the North American low point at Badwater Basin to the highest point of the contiguous United States, less than 100 miles (160 km) away at the summit of Mount Whitney. The region spans several physiographic divisions, biomes, ecoregions, and deserts.

Lake Bonneville pluvial lake

Lake Bonneville was a prehistoric pluvial lake that covered much of the eastern part of North America's Great Basin region. Most of the territory it covered was in present-day Utah, though parts of the lake extended into present-day Idaho and Nevada. Lake Bonneville existed until about 14,500 years ago, when a large portion of the lake was released through the Red Rock Pass in Idaho. Following the Bonneville flood, as the release is now known, the lake receded to a level called the Provo Level. Many of the unique geological characteristics of the Great Basin are due to the effects of the lake.

Sevier River river in the United States of America

The Sevier River is a 385-mile (620 km)-long river in the Great Basin of southwestern Utah in the United States. Originating west of Bryce Canyon National Park, the river flows north through a chain of high farming valleys and steep canyons along the west side of the Sevier Plateau, before turning southwest and terminating in the endorheic basin of Sevier Lake in the Sevier Desert. It is used extensively for irrigation along its course, with the consequence that Sevier Lake is usually dry.

Great Basin Desert desert in the United States

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. It is a temperate desert with hot, dry summers and snowy winters. The desert spans a large part of the state of Nevada, and extends into western Utah, eastern California, and Idaho. The desert is one of the four biologically defined deserts in North America, in addition to the Mojave, Sonoran, and Chihuahuan Deserts.

Nevada Territory

The Territory of Nevada was an organized incorporated territory of the United States that existed from March 2, 1861, until October 31, 1864, when it was admitted to the Union as the State of Nevada.

State of Deseret provisional state of the United States between 1849–1850

The State of Deseret was a provisional state of the United States, proposed in 1849 by settlers from The Church of Jesus Christ of Latter-day Saints in Salt Lake City. The provisional state existed for slightly over two years and was never recognized by the United States government. The name derives from the word for "honeybee" in the Book of Mormon.

Virgin River river in Nevada, United States

The Virgin River is a tributary of the Colorado River in the U.S. states of Utah, Nevada, and Arizona. The river is about 162 miles (261 km) long. It was designated Utah's first wild and scenic river in 2009, during the centennial celebration of Zion National Park.

Indigenous peoples of the Great Basin Native Americans of the northern Great Basin, Snake River Plain, and upper Colorado River basin

The Indigenous Peoples of the Great Basin are Native Americans of the northern Great Basin, Snake River Plain, and upper Colorado River basin. 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, in what is now Nevada, and parts of Oregon, California, Idaho, Wyoming, and Utah. The Great Basin region at the time of European contact was ~400,000 sq mi (1,000,000 km2). There is very little precipitation in the Great Basin area which affects the lifestyles and cultures of the inhabitants.

Walker River river in the United States of America

The Walker River is a river in west-central Nevada in the United States, approximately 62 miles (100 km) long. Fed principally by snowmelt from the Sierra Nevada mountains of California, it drains an arid portion of the Great Basin southeast of Reno and flows into the endorheic basin of Walker Lake. The river is an important source of water for irrigation in its course through Nevada; water diversions have reduced its flow such that the level of Walker Lake has fallen 160 feet (49 m) between 1882 and 2010. The river was named for explorer Joseph Reddeford Walker.

Arizona Strip part of Arizona north of the Colorado River, having more physical/cultural connections with southern Utah and Nevada than the rest of Arizona due to the difficulty of crossing the Grand Canyon, whose largest settlements are Colorado City and Fredonia

The Arizona Strip is the part of Arizona lying north of the Colorado River. The difficulty of crossing the Grand Canyon causes this region to have more physical and cultural connections with southern Utah and Nevada than with the rest of Arizona. The largest settlements in the Strip are Colorado City and Fredonia.

U.S. Route 50 (US 50) is a transcontinental highway in the United States, stretching from West Sacramento, California, in the west to Ocean City, Maryland, on the east coast. The Nevada portion crosses the center of the state and was named The Loneliest Road in America by Life magazine in July 1986. The name was intended as a pejorative, but Nevada officials seized it as a marketing slogan. The name originates from large desolate areas traversed by the route, with few or no signs of civilization. The highway crosses several large desert valleys separated by numerous mountain ranges towering over the valley floors, in what is known as the Basin and Range province of the Great Basin.

Eldorado Valley valley in Nevada, United States of America

Eldorado Valley, or El Dorado Valley, is a Great Basin valley in the Mojave Desert southeast of Las Vegas and southwest of Boulder City, Nevada. The valley is endorheic, containing the Eldorado Dry Lake. The Great Basin Divide, transects ridgelines and saddles, on the north, northeast, east, and south around the valley, as the valley sits on the east of the McCullough Range, a Great Basin massif, on the Great Basin Divide at its north terminus and its south terminus.

Bull Valley Mountains

The Bull Valley Mountains are a 30-mi (48 km) long, mountain range in southwest Utah, located in northwest Washington County. The range is adjacent the Utah border and attached to the Clover Mountains of southeast Nevada. The Great Basin Divide transects the summits of both ranges, with the Escalante Desert north and northeast of the Bull Valley Mountains, and south of the mountains the Colorado River watershed, and specifically the Santa Clara River which drains southeasterly from an escarpment along the mountain range's southeast flank.

Peacock Mountains

The Peacock Mountains are a small, 26-mi (42 km) long mountain range in northwest Arizona, USA. The range is a narrow sub-range, and an extension north, at the northeast of the Hualapai Mountains massif, which lies to the southwest. The range is defined by the Hualapai Valley to the northwest, and north and south-flowing washes on its east border, associated with faults and cliffs; the Cottonwood Cliffs are due east, and are connected to the Aquarius Cliffs southward at the west perimeter of the Aquarius Mountains; the cliffs are a result of the Aquarius Fault, which is an extension southward from the Grand Wash Cliffs and Grand Wash Fault which crosses the Colorado River at Lake Mead, and the west perimeter of the Grand Canyon/Colorado Plateau.
