Whitmore Hot Springs
Whitmore Hot Springs flows at 95 degrees Fahrenheit near Mammoth Lakes at 6,970 feet elevation, with recent USGS measurements recording 96.2 degrees Celsius (205°F), suggesting either multiple thermal features or measurement variation. Water chemistry shows alkaline conditions with 183 milligrams per liter of chloride in high elevation terrain.
The spring sits in the high desert landscape of the Owens Valley's eastern margin, surrounded by pinyon-juniper forest and sagebrush typical of 7,000-foot elevations. A short walk from the road accesses the thermal feature in terrain managed by the Los Angeles Department of Water and Power. Winter snowfall of 83.6 inches annually transforms this landscape seasonally, creating stark seasonal contrasts.
Access requires a 293-meter walk from the parking area, classified as a short approach in typical conditions. Heavy snow from November through April may impede access in winter, though summer and fall provide excellent visiting conditions. Expect cold air temperatures year-round despite hot water. Bring warm clothing and plan for quick transitions between cold air and hot water.
Whitmore Hot Springs emerges from deep geothermal circulation in terrain shaped by Basin and Range geology and Mammoth's active geothermal system. The extreme USGS temperature reading (if accurate) would place this among California's hottest springs, suggesting geothermal activity related to the Long Valley Caldera system. Historical use and current access restrictions reflect management concerns about resource protection.
The water at Whitmore Hot Springs is alkaline (pH 8.7). It is notably rich in chloride (natural antiseptic with skin health benefits).
