The Black Rock Desert is a semi-arid region (in the Great Basin shrub steppe, 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 lake bed that is a dry remnant of Pleistocene Lake Lahontan.

The average annual precipitation (years 1971-2000) at Gerlach, Nevada (extreme south-west of the desert) is 7.90 inches (200 mm). 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 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 festival.
