Warm Spring
This thermal spring emerges in the Modoc National Forest near Tulelake at 5,204 feet elevation. Situated on US Forest Service land with guaranteed public access, it represents the volcanic-dominated geothermal systems of northeastern California's remote highlands.
The spring flows through National Forest terrain characterized by ponderosa pine and mixed conifers at the edge of the Great Basin. A 600-meter walk from 46540D Road brings you into a landscape where volcanic geology and continental drainage create a unique geothermal environment far from developed areas.
The Modoc National Forest encompasses some of Oregon and California's most active geothermal regions, shaped by Cascade Range volcanism and Basin and Range extension. Springs here reflect deep circulation of groundwater through fractured volcanic rock and basin faults.
Public access is guaranteed on US Forest Service land under multiple-use protection guidelines. The short walk from 46540D Road provides straightforward access for visitors exploring this remote corner of the Forest Service system in Siskiyou County.
