Unnamed Thermal Spring
This modest 75-degree thermal spring emerges over 1,100 meters from the nearest road in Fresno County's remote hills near Firebaugh, where hot springs remain uncommon.
The spring flows from Bureau of Land Management property in rolling foothill terrain at 962 feet elevation. Desert scrub and grassland vegetation dominate the landscape, with limited water sources making the thermal pool a notable feature in this arid environment.
Access requires hiking over 1,100 meters from the road into open public lands. The remote setting near Firebaugh offers solitude and open access year-round. Expect hot, dry conditions during summer months with minimal precipitation—averaging just 10 inches annually.
The 9-degree temperature rise above ambient suggests modest geothermal circulation in a region not typically associated with significant thermal activity. BLM's Central Coast Field Office manages the site under multiple-use regulations that permit recreation alongside other land uses.
