Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.

A state-run public access site in the dry country of western Fresno County, about thirteen miles out of Coalinga, with water that comes up hot. The record lists it as open, and the spring sits close beside the road that carries its name. No water chemistry is on record and the listing carries no campground.

Location

Coalinga Mineral Springs Road runs right past it. From the road you cover under three hundred feet to reach the water. The land is a state public access parcel named for the spring itself and flagged as a recreation site. Elevation is missing from the record. Rainfall is scant and snow does not happen; the yearly average temperature is mild.

Winter is the season the record favors, December through February, when hot water makes sense against cool air. Access is roadside, so no walking to speak of. The water is hot enough that you will want to test it with a hand before sitting down. Nothing on file covers fees or hours, and no campground is tied to this spring, so plan to sleep in Coalinga or bring your own arrangements.

Heat Below
81 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 17% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
