Little Hot Creek Spring discharges at 180°F with alkaline chemistry (pH 7.8) and moderate mineral content dominated by sodium chloride in the Sierra Nevada high country. Sitting at 7,035 feet in the Inyo National Forest near Mammoth Lakes, this superheated spring rises 135 degrees above ambient in a snow-heavy climate.

A short walk from Antelope Springs Road crosses montane meadows and mixed conifer forest to reach Little Hot Creek at nearly 7,000 feet elevation. Clear, extremely hot water emerges from granitic bedrock and flows into a small pool surrounded by whitebark pine and wildflowers in season. The stream drops sharply downslope through rocky terrain beneath towering Sierra peaks visible across the Long Valley Caldera.

History of Little Hot Creek Spring

Little Hot Creek Spring (also called Little Creek Hot Springs) flows from geothermally heated groundwater circulating deep beneath the Long Valley Caldera, a massive volcanic depression formed 700,000 years ago. The water's alkaline signature and sodium-chloride composition reflect heating in volcanic rocks. USGS measurements confirm 82.7°C (181°F) discharge temperature.

This backcountry spring requires a short hike from Antelope Springs Road. The harsh alpine environment—78.8 inches of annual snow and 45°F average air temperature—makes summer (July-September) the practical visit window. Water is extremely hot; never submerge unaccustomed skin directly. The remote setting demands proper wilderness preparation and respect for the powerful thermal feature."
