Unit 013 takes in the Owyhee River drainage and surrounding desert in extreme north-central Nevada along the Idaho border. The country is high-desert sage, pinon-juniper benches, and the dramatic basalt canyons cut by the Owyhee and its tributaries. Elevations span from about 4,500 feet in the river canyons to roughly 8,000 feet on the rim country. The river canyons are deep, brushy, and full of cliff bands—the country looks gentle until you try to cross it. Almost all BLM with the Duck Valley Indian Reservation forming the northern boundary (closed without tribal permits—and they actively check). The Owyhee River has wilderness designation in stretches, restricting motorized access. State Route 225 from Elko to Owyhee is the main road; from there, BLM tracks branch into the desert. Owyhee is a small reservation town with limited services; Mountain City has fuel; Elko (90 miles south) is the supply hub. Cell service is on Route 225 weakly and gone in the canyons. Mule deer use the canyon rim country and the mahogany pockets; California bighorn sheep inhabit the canyons themselves with very limited tags. The country is empty in the truest sense—plan for self-rescue.
