Unnamed Thermal Spring
This federally managed spring in Pershing County discharges at 172°F, ranking among Nevada's hottest thermal features with water emerging 118 degrees above ambient air temperature. Recent USGS analysis confirmed 46.7°C water with neutral pH 7.1 and elevated sodium (300 mg/L), chloride (160 mg/L), and sulfate (140 mg/L).
The spring sits at 3,953 feet elevation in the arid basin country south of the Black Rock Desert, roughly 1,700 feet from the nearest road on Bureau of Land Management property managed by the Black Rock Field Office. The surrounding landscape receives only 7.1 inches of annual precipitation with 12.7 inches of snow, supporting sparse desert vegetation adapted to extreme temperature swings. Lovelock lies to the south, and the terrain consists of alkali flats and low hills typical of Nevada's Great Basin physiography.
The spring's name remains unrecorded in available documentation, and historical records provide limited detail on Indigenous use or early Euro-American discovery. Bureau of Land Management designation as PUB (public) land with protection status 3 indicates the area remains subject to extractive uses including grazing and mineral development while maintaining open public access.
Visit during spring or fall when air temperatures moderate; summer heat compounds the already extreme thermal output, and winter brings occasional snow to this high desert environment. The 518-meter walk from the nearest road requires no permit for day use. Bring adequate water, sun protection, and sturdy footwear for unimproved terrain. Observe water temperature carefully before any contact.
