The Groom Range is a mountain range in Lincoln County, Nevada. [1] The range was renamed from Naquinta Mountains or Tequima Range in 1864, after Bob Groom, who discovered minerals in the range. [2] It is located within the Nevada Test and Training Range, north of Groom Dry Lake. The highest point in the Groom Range is 9,249 feet. The Groom Range is situated 26.6 miles north of the dry Groom Lake.
Lincoln County is a county located in the U.S. state of Nevada. As of the 2010 census, the population was 5,345. Its county seat is Pioche.
Nevada is a state in the Western United States. It is bordered by Oregon to the northwest, Idaho to the northeast, California to the west, Arizona to the southeast and Utah to the east. Nevada is the 7th most extensive, the 32nd most populous, but the 9th least densely populated of the U.S. states. Nearly three-quarters of Nevada's people live in Clark County, which contains the Las Vegas–Paradise metropolitan area where three of the state's four largest incorporated cities are located. Nevada's capital, however, is Carson City.
The Nevada Test and Training Range (NTTR) is one of two military training areas used by the United States Air Force Warfare Center at Nellis Air Force Base in Nevada. The NTTR land area includes a "simulated Integrated Air Defense System", several individual ranges with 1200 targets, and 4 remote communication sites. The current NTTR area and the range's former areas have been used for aerial gunnery and bombing, for nuclear tests, as a proving ground and flight test area, for aircraft control and warning, and for Blue Flag, Green Flag, and Red Flag exercises.
The United States Air Force facility commonly known as Area 51 is a highly classified remote detachment of Edwards Air Force Base, within the Nevada Test and Training Range. According to the Central Intelligence Agency (CIA), the correct names for the facility are Homey Airport and Groom Lake, though the name Area 51 was used in a CIA document from the Vietnam War. The facility has also been referred to as Dreamland and Paradise Ranch, among other nicknames. USAF public relations has referred to the facility as "an operating location near Groom Dry Lake". The special use airspace around the field is referred to as Restricted Area 4808 North (R-4808N).
Groom Lake is a dry lake. Also described as a salt flat, it is located in Nevada, and used for runways of the Nellis Bombing Range Test Site airport (KXTA). Part of the Area 51 USAF installation, it lies at an elevation of 4,409 ft (1,344 m) and is approximately 3.7 miles (6.0 km) from north to south and 3 miles (4.8 km) from east to west at its widest point, and is approximately 11.3 miles in circumference. Located within the namesake Groom Lake Valley portion of the Tonopah Basin, the lake is 25 mi (40 km) south of Rachel, Nevada.
The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, a chain of mountain ranges that consists of an almost continuous sequence of such ranges that form the western "backbone" of North America, Central America, South America and Antarctica.
California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is geographically diverse. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the major geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states. The state is generally divided into Northern and Southern California, although the boundary between the two is not well defined. San Francisco is decidedly a Northern California city and Los Angeles likewise a Southern California one, but areas in between do not often share their confidence in geographic identity. The US Geological Survey defines the geographic center of the state at a point near North Fork, California.
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.

The Carson Range is a spur of the Sierra Nevada in eastern California and western Nevada that starts at Carson Pass and stretches north to the Truckee River near Verdi, Nevada.
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.
The Ruby Mountains are a mountain range, primarily located within Elko County with a small extension into White Pine County, in Nevada, United States. Most of the range is included within the Humboldt-Toiyabe National Forest. The range reaches a maximum elevation of 11,387 feet (3,471 m) on the summit of Ruby Dome. To the north is Secret Pass and the East Humboldt Range, and from there the Rubies run south-southwest for about 80 miles (130 km). To the east lies Ruby Valley, and to the west lie Huntington and Lamoille Valleys. The Ruby Mountains are the only known range of an introduced bird, the Himalayan snowcock, in North America.
The Pahranagat Valley is a Tonopah Basin landform in Lincoln County, Nevada.
Tonopah Test Range Airport, at the Tonopah Test Range is 27 NM southeast of Tonopah, Nevada and 140 mi (230 km) northwest of Las Vegas, Nevada. It is a major airfield with a 12,000 ft × 150 ft runway, instrument approach facilities, and nighttime illumination. The facility boasts over fifty hangars and an extensive support infrastructure.
The Fish Lake Valley is a 25 miles (40 km) long endorheic valley in southwest Nevada, one of many contiguous inward-draining basins collectively called the Great Basin. The alluvial valley lies just northwest of Death Valley and borders the southeast, and central-northeast flank of the massif of the White Mountains of California. The valley's southern end lies in eastern Inyo County, California. The valley is sparsely populated with ranchers and indigenous Paiute. Business services are located in the valley's only town Dyer.
The Piute Valley is a 45-mile-long (72 km) north–south valley southeast of Las Vegas, Nevada, and northwest of Needles. The north of the valley is at Searchlight, with some of the valley extending northwest from Searchlight. At the center-north lies Cal-Nev-Ari, Nevada.
Pahrump Valley is a Mojave Desert valley west of Las Vegas and the Spring Mountains massif in southern Nye County, Nevada, and eastern San Bernardino County, California. Pahrump, Nevada, is in the valley's center and the Tecopa and Chicago Valleys are immediately to the west. The valley has routes to Death Valley and a route to Las Vegas.
The Nellis (AFB) - National Wildlife five contiguous range region contains two wildlife ranges and three United States government agency regions. They form a contiguous region of mountain ranges, valleys, dry lakes, special landforms, and test sites in southeast Nevada, north and northwest of Las Vegas, Nevada.
Indian Springs Valley is one of the Central Nevada Desert Basins in the Clark County portion of the Nevada Test and Training Range and includes Creech Air Force Base and the communities of Cactus Springs and Indian Springs, Nevada. The south side of the valley is along the "Las Vegas Valley Shear Zone", and to the east is the Pintwater Range, to the southeast is the Las Vegas Valley, to the south are foothills near the Spring Mountains, to the southwest is Mercury Valley, and to the west is the Spotted Range. The valley's drainage basin receives ~500 acre feet (620,000 m3) of annual precipitation and is a southern portion of the Sand Springs-Tikaboo Watershed where it meets the Ivanpah-Pahrump Watershed. The Wheeler Survey in 1869 passed through the Indian Springs Valley.
Groom Mine, located in Lincoln County, Nevada, first opened in the 1870s. Most mining in the area, mostly of silver chloride ores, had finished by 1874. Groom Mine continued to operate, finally ceasing operations in 1954. By 1956, official recordings of products of the Groom Mining District, which includes Groom Mine, shows that lead was the bulk of minerals harvested, which also included 145,000 troy ounces (4,500 kg) of silver and about 45 troy ounces (1.4 kg) of gold. During World War II, Groom Mine became surrounded by military activity, which continued into the 21st century. In the 1950s, the mine was exposed to fallout from nuclear testing that was being carried out at the Nevada Test Site. During the late 20th century, military activities, including the destruction of a mill and the restriction of access to the mine, continued to affect work there. The United States Government seized the mine under eminent domain from its previous owners in 2015.
The geology of Nevada began to form in the Proterozoic at the western margin of North America. Terranes accreted to the continent as a marine environment dominated the area through the Paleozoic and Mesozoic periods. Intense volcanism, the horst and graben landscape of the Basin and Range Province originating from the Farallon Plate, and both glaciers and valley lakes have played important roles in the region throughout the past 66 million years.
