Blaney Meadows Hot Springs
Blaney Meadows Hot Springs emerges at 109 degrees Fahrenheit from the Sierra National Forest at 7,676 feet elevation, delivering geothermal warmth in an alpine environment receiving 209 inches of annual snowfall.
The spring sits 337 feet from the nearest road at a mountain meadow surrounded by aspen and lodgepole pine, where the South Fork of the San Joaquin runs through. The landscape appears virtually snow-covered from November through May, making the warm spring water especially vital for wildlife throughout the extended winter season.
Access requires a short walk from parking areas into wilderness. The spring lies near Native American archaeological sites with significant cultural importance. Best visited during summer months when snow clears and mountain roads become accessible. Jackass Meadow Campground, 9 kilometers away, offers the nearest developed camping, though hazard tree removal may affect availability.
The spring emerges on federally managed US Forest Service land in the John Muir Wilderness area, where geothermal circulation brings heated water to the surface through fractured alpine bedrock. The 65-degree temperature rise above ambient demonstrates active geothermal circulation even at this high elevation, suggesting deep subsurface heat sources.
