A 126°F hot spring at 4,494 feet elevation near the Oregon-Nevada border, administratively listed under Nevada's Humboldt County near Winnemucca. The spring runs 75 degrees above the 51.4°F ambient air temperature, indicating robust geothermal activity. Access requires a 6,960-foot hike from I.O.N. Highway across remote high desert terrain.

The spring emerges in the arid landscape of the northern Great Basin at 4,494 feet elevation, surrounded by sagebrush steppe, alkali flats, and scattered juniper characteristic of the Oregon-Nevada border region. The area receives just 10.5 inches of annual precipitation and 26.2 inches of snow annually. The remote location sits in sparsely populated territory where vast distances separate scattered ranches and roads. Surrounding topography consists of basin and range geology typical of this extensional tectonic province.

History of This Spring

Historical documentation is limited for this remote thermal feature. The administrative listing under Humboldt County, Nevada, despite proximity to the Oregon border, reflects the complex jurisdictional boundaries in this isolated region. The I.O.N. Highway reference suggests association with historical transportation corridors connecting interior communities. Indigenous use of thermal springs throughout the Great Basin is well documented, though specific records for this site are not available in current data.

The 1.3-mile hike from I.O.N. Highway crosses unimproved high desert terrain. Bring adequate water, navigation tools, and be prepared for rapid weather changes at this elevation. The 126°F temperature makes the spring dangerous for bathing without cooling. Verify current land ownership and access permissions before visiting. Summer heat can be extreme in this exposed landscape, while winter brings snow and freezing temperatures. The remote location requires self-sufficiency and appropriate desert travel preparation.
