Chance Spring
Chance Spring emerges modestly at 73 degrees Fahrenheit from land managed by Los Angeles Department of Water and Power near Mammoth Lakes. This cooler thermal feature contrasts with neighboring Casa Diablo springs in the geothermal Long Valley region, requiring only a short 440-foot walk from the nearest access point.
The spring sits at 7,200 feet elevation where alpine terrain and sparse vegetation characterize the landscape around this modest thermal feature. Water emerges in the shadow of the eastern Sierra Nevada crest, where annual snowfall exceeds 98 inches and the climate remains cool and relatively dry despite elevation.
This short walk makes it highly accessible despite the high elevation. The modest water temperature permits closer approach than neighboring Casa Diablo features, though exercise normal thermal feature safety protocols. Summer access (July through September) avoids heavy snow; winter closures are common. Sherwin Creek Campground is 4.6 kilometers away.|
Chance Spring exemplifies the complex water-rights landscape of the Eastern Sierra, where Los Angeles has maintained control over significant geothermal and groundwater resources. The spring's moderate temperature and high pH (8.7) with elevated total dissolved solids (1,410 mg/L) indicate interaction with the same Long Valley Caldera system.
The water at Chance Spring is alkaline (pH 8.7) with 1410 mg/L total dissolved solids. It is notably rich in sodium (supports circulation and skin hydration), chloride (natural antiseptic with skin health benefits), and total dissolved solids (higher mineral concentration for therapeutic soaking).
