Black Rock Hot Spring — by Mitch Barrie — CC BY-SA 2.0
— Source
This unnamed spring produces 194°F water in Pershing County, ranking among Nevada's hottest thermal features at 139.9 degrees above the 54.1-degree ambient temperature, with USGS analysis confirming 89.2°C water temperature and extremely high sodium-chloride content of 1,500 and 1,700 mg/L respectively.
Emerging at 3,950 feet elevation on BLM Black Rock Field Office lands, the spring sits in basin terrain receiving just 7.2 inches of precipitation and 12.2 inches of snow annually. The location lies 1,298 meters from the nearest road, requiring a walk across open desert where summer heat and winter cold create temperature extremes. The neutral pH of 7.0 and high mineral content indicate deep circulation through fault systems.
History of This Spring
No documented name or development history exists for this spring. The site's position on federal public land subject to extractive use suggests it has remained in natural state, known primarily through government geothermal surveys rather than recreational or commercial development.
The short walk crosses unshaded desert where summer temperatures regularly exceed 100°F. Carry adequate water and sun protection. Winter access may be complicated by mud following rare precipitation events. The extremely hot water temperature and high mineral content make this strictly an observation site, not suitable for bathing.
