Black Rock Desert 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 "(years 1971-2000)" at Gerlach, Nevada (extreme south-west of the desert) is . 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
Bonneville Salt Flats ShootOut in September. The Southern California Timing Association and the Utah Salt Flats Racing Association organizes and plans the multi-vehicle events, but all event promoters contribute to prepping and maintaining the salt. "Speed Week" events in August were canceled for the second year in a row in 2015, due to poor conditions of the salt in certain parts of the flats. The salt flats had been swamped by heavy rains earlier in the year, which usually happens, but the rains also triggered mudslides from surrounding mountains and onto a section of the flats used for the land-speed racing courses.
