Alpine Warm Spring
Alpine Warm Spring emerges at 99°F near Hoback at 5,580 feet elevation, maintaining water 55.6°F above ambient in mountain terrain. The spring's robust discharge and elevated mineral content reflect circulation through deep geothermal pathways in the Palisades Reservoir area.
The spring flows from volcanic rock in high mountain terrain where winters deliver 137 inches of snow annually. Water emerges noticeably warm amid spruce-fir forest in an environment where ambient temperatures average 43.4°F, creating visible steam in cold seasons.
Access requires 0.8 miles of hiking from US Highway 26 via short walk. Snow can block routes from November through April. Blowout Campground 1.9 miles distant offers RV-accessible camping with 30 developed sites at 5,700 feet elevation.
Alpine Warm Spring's high sodium and chloride content suggests deep groundwater circulation through ancient mineral-bearing formations underlying the Palisades area. Heat and mineral enrichment together indicate long subsurface residence time before emergence.
The water at Alpine Warm Spring is slightly acidic (pH 6.5). It is notably rich in calcium (may support bone density and joint health), magnesium (known for muscle relaxation and stress relief), and sodium (supports circulation and skin hydration).
