The Black Rock Desert is a semi-arid region, 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 north of Reno, Nevada that encompasses more than 300,000 acres of land and contains more than 120 miles of historic trails. It is in the northern Nevada section of the Great Basin with a lakebed, 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. The average annual precipitation at Gerlach, Nevada is 7.90 inches. The region is notable for its paleogeologic features, as an area of 19th-century Emigrant Trails to California, as a venue for rocketry, as an alternative to the Bonneville Salt Flats in northwestern Utah, for setting land speed records, it is the location for the annual Burning Man event.
The Black Rock Desert is part of the National Conservation Area, a unit of the Bureau of Land Management National Landscape Conservation System. The NCA is located in northwest Nevada, was established by legislation in 2000, it is a unique combination of desert playa, narrow canyons, mountainous areas. Humans have been in Black Rock Desert since 10,000 B. P. Around 1300 AD the area was settled by the Paiute people; the large black rock formation was used as a landmark by the Paiute and emigrants crossing the area. The landmark is a conical outcrop composed of interbedded Permian marine limestone and volcanic rocks. At its base is a large hot spring and grassy meadow, an important place for those crossing the desert headed for California and Oregon. In 1843, John Fremont and his party were the first white men to cross the desert, his trail was used by over half the 22,000 gold seekers headed to California after 1849. In 1867, Hardin City, a short-lived silver mill town was established; the Black Rock Desert region is in the northwestern Great Basin.
The playa extends for 100 mi northeast from the towns of Gerlach and Empire, between the Jackson Mountains to the east and the Calico Hills to the west. The Black Rock Desert is separated into two arms by the Black Rock Range, it has an area of about 1,000 sq mi. There are several possible definitions of the extent of the Black Rock Desert. People refer just to the playa surface. Sometimes terrain which can be seen from the playa is included; the widest definition of the Black Rock Desert region is the watershed of the basin that drains into the playa. The intermittent Quinn River is the largest river in the region, starting in the Santa Rosa Range and ending in the Quinn River Sink on the playa south of the Black Rock Range; the watershed covers 11,600 sq mi including the Upper and Lower Quinn River, Smoke Creek Desert, Massacre Lake, Thousand Creek/Virgin Valley watersheds of northwestern Nevada as well as small parts across the borders of California and Oregon. If the playa is wet for a month or so, the shallow waters teem with fairy shrimp, or anostraca born of eggs that lie dormant in the silt crust for long periods of time - sometimes for many years.
The edges of the playa and the Quinn River Sink stay wet longer than the rest of the playa, which concentrates the fairy shrimp and migratory birds in those areas. More than 250 species of neo-tropical migrant birds and many other water birds stop in Black Rock-High Rock Country for varying lengths of time; when wet in spring, the playa is a favorite place for these winged visitors to rest and feed. When it rains, the playa can become sticky, bogging down four-wheel-drive vehicles; some areas of the Black Rock are environmentally closed to all vehicles. Humboldt and Washoe Counties of Nevada intersect at the Black Rock Desert; the following mountain ranges are within. The desert has numerous volcanic and geothermal features of the northwest Nevada volcanic region, including two Black Rock Points at the southern end of the Black Rock Range and which have dark Permian volcanic rocks similar to another Permian black diabase dike formation in Nevada; the portion of the Lake Lahontan lakebed in the Black Rock Desert is flat with Lahontan salt shrub vegetation scattered hot springs, a playa.
In areas of the lakebed along mountains, rain shadow results in desert precipitation levels. The playa of the Black Rock Desert lakebed is ~200 sq mi within an area bounded by the Calico Mountains Wilderness, the Applegate National Historic Trail, the Union Pacific Railroad; the "South Playa" is between Gerlach and the southwest boundary of the National Conservation Area, while the northeast NCA portion of the playa is between the NCA boundary and the Applegate National Historic Trail. A Nobles route between Gerlach and Black Rock Hot Springs extends through the length of the playa; the playa's Quinn River Sink of ~3 sq mi is where the Quinn River discharges/evaporates ~2.75 mi south-southwest of Black Rock Hot Springs. Prospecting and mining has occurred in the Black Rock region since the mid-19th century. US Gypsum Corporation operated a gypsum mine and drywall manufacturing plant in Empire
