Sou (Seven Devils) Hot Springs
Sou Hot Springs, also known as Seven Devils Hot Springs, emerges at 185 degrees in Pershing County, Nevada, ranking among the hottest thermal springs in the United States. Recent USGS measurements confirm 62.1°C at this roadside feature just 15.3 meters from pavement at 3,700 feet elevation. Water chemistry shows 1,010 mg/L total dissolved solids with neutral pH of 6.9.
The springs discharge in northwestern Nevada's basin terrain where geothermal gradients produce extreme temperatures. The roadside location provides immediate access to view the thermal activity. Annual precipitation totals 8.3 inches with 14.2 inches of snow and average air temperatures of 58.4 degrees in this arid environment. The springs maintain temperatures 126.6 degrees above ambient, creating visible steam discharge. Surrounding vegetation consists of salt-tolerant desert shrubs adapted to thermal seeps.
The scalding 185-degree temperatures absolutely preclude any bathing or direct contact. Visit to observe extreme geothermal discharge from a safe distance. The roadside location eliminates hiking but requires caution around steam and hot water. Accessible year-round via paved approach. Bring camera equipment for documenting this rare high-temperature thermal feature in a desert setting.
The dual names Sou Hot Springs and Seven Devils Hot Springs both appear in historical records, though the origin of either designation remains unclear in available documentation. The springs appear in the 1980 NOAA inventory as a significant high-temperature thermal feature.
