The Black Rock Desert-High Rock Canyon Emigrant Trails National Conservation Area is vast wilderness landscape in northwestern Nevada, home to lava flows, enormous alkali lake beds, intricate desert canyons, soaring vistas and diverse wildlife. The NCA protects 120 miles of the most pristine Western stretches of the historic emigrant trails and wagon ruts, including the Applegate-Lassen section of the California National Historic Trail. 

Spectacular scenic opportunities abound in one of the largest and flattest alkaline playas in the United States. The Playa is a now-dry remnant of ancient Lake Lahontan; it is 44 miles long (oriented north-south), and averages 7 miles in width. Interesting geologic features dominate the landscape, and opportunities for solitude abound.

Each Labor Day week, the Black Rock Playa is also the location of the world-famous Burning Man Festival.
