Warm Spring emerges at 75°F on the high plateau of northeastern California, rising 24.1 degrees above the 50.9°F annual average. This modest thermal resource appears in remote sagebrush terrain far from population centers or developed infrastructure.

Location

The spring sits at 4,404 feet elevation in the Basin and Range province, where juniper woodlands and sagebrush steppe dominate the landscape. A half-mile walk from County Road 151 takes you through typical high desert terrain where vistas open across broad valleys hemmed by fault-block mountains.

Access is straightforward via a short walk from County Road 151 in the Modoc National Forest vicinity. Patterson Guard Station, 28.4 km distant, provides the nearest developed recreation amenity for those combining spring exploration with backcountry camping or hiking.

History of Warm Spring

This spring represents another manifestation of the Basin and Range's deep geothermal system, where regional faulting allows groundwater to circulate to depths where crustal heat warms the water. The Modoc plateau's volcanic history and ongoing extension create the thermal conditions.
