Mize Spring
Mize Spring produces lukewarm 73°F water in the arid Temblor Range near Lost Hills, a remote location where the modest 8-degree temperature rise above ambient reflects the spring's modest geothermal character. This subtle thermal feature rewards visitors seeking solitude and minimal-impact geothermal exploration in California's least-visited foothills.
The spring emerges at 1,557 feet elevation in rolling grassland and oak woodland typical of western Kern County's inland foothills. The approach requires traversing over a mile of dry terrain through scattered vegetation and sandy washes; the spring itself collects in small natural pools surrounded by the subtle landscape beauty of semi-arid California foothills far from tourist infrastructure.
Mize represents a modest geothermal feature in a region where thermal springs are uncommon. The 8-degree temperature differential above the 64.8°F ambient air suggests relatively shallow circulation—perhaps 200-300 feet deep through local bedrock. The remote location and limited thermal output meant minimal historical development; the spring remains essentially undisturbed and little-known.
This is a genuine backcountry hike requiring navigation and substantial effort—over 1.7 miles from the nearest road through rugged terrain. Visit October through April when desert temperatures are manageable; summer heat makes the hike hazardous. Bring abundant water, sun protection, and navigation tools. The Temblor Range remains sparsely visited; solitude is guaranteed but requires genuine backcountry competence.
