Unnamed Thermal Spring
Rising to 102°F at 4,332 feet elevation, this unnamed spring requires a 1,130-foot walk to reach waters flowing 49 degrees above ambient temperature. Recent USGS measurements confirmed 52.2°C in this high desert environment near the California-Nevada border south of Alturas.
The spring emerges at 4,332 feet where annual precipitation averages just 9.8 inches including 26.7 inches of snow, supporting mean air temperatures of 52.9°F. High desert vegetation dominates the landscape, characterized by sagebrush and native grasses adapted to arid conditions. The thermal waters flow in country receiving less than 10 inches of rain annually.
No documented name, ownership information, land management agency, or historical record exists for this spring. The absence of administrative data suggests a remote or less-studied thermal feature.
Quarter-mile walk requires sturdy footwear and water. Visit during spring or fall when temperatures are moderate. Water temperature of 102°F is suitable for soaking. Lack of land management information suggests verifying access legality before visiting.
