Darroughs Hot Springs
Darroughs Hot Springs discharges water at 203°F, ranking among Nevada's highest-temperature geothermal features. Recent USGS measurements confirmed 100°C at the source, producing water with extremely low magnesium (0.02 mg/L) and moderate sodium (111 mg/L) typical of deep-circulation thermal systems. The spring emerges 91.3 meters from the nearest road at 5,600 feet elevation near Tonopah, flowing 149.7°F above ambient air temperature.
The spring flows from volcanic terrain in the Big Smoky Valley region of central Nevada, where Basin and Range faulting creates pathways for superheated groundwater to reach the surface. At 5,600 feet elevation, the site receives 10.5 inches of annual precipitation and substantial winter snowfall (39.2 inches), with average air temperatures of 53.3°F. The surrounding landscape bears the marks of Nye County's mining heritage, with tailings and abandoned workings scattered across sagebrush-covered slopes where silver and gold discoveries drove boom-and-bust cycles for over a century.
The spring takes its name from early rancher or prospector Darrough, though specific details of this individual's activities remain poorly documented in available sources. The feature would have been noted by Indigenous peoples and later by miners working the Tonopah district, which experienced major silver discoveries beginning in 1900. The extreme temperatures prevented direct use for bathing but likely attracted attention for industrial applications.
The boiling temperature makes this spring dangerous for recreational use; observe from a safe distance and prevent children or pets from approaching the outflow. Winter conditions at this elevation can be severe with snow closures; spring through fall offers the most reliable access. The site lies within reach of Tonopah's historic mining district and several other central Nevada thermal features. High-clearance vehicles recommended for final approach.
