The Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area is the federal land in northwestern Nevada, under the Bureau of Land Management-BLM management and protection, and the ten Wilderness Areas within it. The long name has led people to often shorten it to the Black Rock–High Rock NCA, when not needing the official name. The protected areas were created by the Black Rock Desert–High Rock Canyon Emigrant Trails National Conservation Area Act of 2000.
