The Black Rock Desert is a semi-arid region (in the Great Basin shrub steppe ecoregion) of lava beds and playa, or alkali flats, situated in the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area, a silt playa 100 miles (160 km) north of Reno, Nevada, that encompasses more than 300,000 acres (120,000 ha) of land and contains more than 120 miles (200 km) of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed that is a dry remnant of Pleistocene Lake Lahontan.
The Great Basin, named for the geography in which water is unable to flow out and remains in the basin, is a rugged land serrated by hundreds of mountain ranges, dried by wind and sun, with spectacular skies and scenic landscapes.[1] The average annual precipitation (in the years 1971–2000) at Gerlach (in the extreme south-west of the desert) is 7.90 inches (200 mm).[2]
The region is notable for its paleogeologic features, as an area of 19th-century Emigrant Trails to California, as a venue for rocketry, and as an alternative to the Bonneville Salt Flats in northwestern Utah for setting land speed records (Mach 1.02 in 1997). It is also the location for the annual Burning Man event.
The Black Rock Desert is part of the National Conservation Area (NCA), a unit of the Bureau of Land Management (BLM) National Landscape Conservation System (NLCS). The NCA is located in northwest Nevada and was established by legislation in 2000. It is a unique combination of the desert playa, narrow canyons, and mountainous areas.
Humans have been in Black Rock Desert since approximately 10,000 B.P.[3] Around 1300 CE, the area was settled by the Paiute people.[4][5] The Desert's namesake large, black rock formation was used as a landmark by the Paiute and later emigrants crossing the area. The landmark is a conical outcrop composed of interbedded Permian marine limestone and volcanic rocks.[6] At its base is a large hot spring and grassy meadow, which was an important place for those crossing the desert headed for California and Oregon. In 1843, John Frémont and his party were the first white men to cross the desert, and his trail was used by over half of the 22,000 gold seekers headed to California after 1849. In 1867, Hardin City, a short-lived silver mill town, was established (now a ghost town).

Layton suggests little use of the High Rock Country from ca. AD 200–1300, with the population possibly emigrating to Surprise Valley.
When the first white man arrived, the region known as northwestern Nevada was occupied by the Northern Paiute people. Cave excavations have provided evidence that these Indians did not come to this section of the Great Basin until approximately 1,400 A.D. and that at least three other separate cultures of people preceded them.
