Blackrock History

The Black Rock Desert is a semi-arid region (in the Great Basin shrub steppe eco-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 (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 average annual precipitation (years 1971-2000) at Gerlach, Nevada (extreme south-west of the desert) is 7.90 inches (200 mm).[7]
