Mustang Springs
Mustang Springs flows at 73 degrees Fahrenheit on BLM land in Pershing County at 5,830 feet elevation, emerging 25 degrees warmer than the 48-degree average air temperature. Managed by the Black Rock Field Office, the spring sits on public land requiring a challenging 2-mile hike from the nearest road access. Recent USGS measurements confirm 73-degree water, barely warm enough for bathing but pleasant for extended soaking.
The spring occupies high-elevation terrain in northwestern Nevada's remote backcountry, surrounded by sagebrush, mountain mahogany, and scattered juniper at elevations approaching 6,000 feet. The Black Rock Desert region extends to the west while the Calico Mountains and other ranges define the broken topography. At this elevation, precipitation totals 9.5 inches annually with 28 inches of snow, creating cold winters with temperatures well below freezing. The landscape consists of exposed volcanic geology, sparse vegetation, and open vistas typical of Nevada's Basin and Range province.
The spring's name likely references wild mustangs that historically roamed northwestern Nevada in large herds, utilizing remote water sources for survival in the arid landscape. The Black Rock Desert country supported extensive populations of feral horses descended from escaped livestock, with springs serving as critical gathering points. Specific historical documentation of human use at Mustang Springs is limited, though Indigenous peoples, trappers, and later ranchers would have known of the water source in this remote terrain.
Visit June through September when snow has melted and access roads are dry; winter conditions make the area impassable. The 2-mile hike requires good fitness and navigation skills across unmarked terrain. Carry adequate water despite the destination spring. The 73-degree water temperature provides modest warmth suitable for cooling after the hike. High elevation brings rapid weather changes; pack layers and rain gear.
