Location
3 miles from El Paso de Robles, CA

Low rolling country at under a thousand feet, with mild winters and dry summers. No snow. North River Road runs right past. Nothing on file names an owner or a land unit, and there is no designation, so it may well be private. No fee is recorded and no bath type.

Winter is what the record recommends, and the wet season here is short. For camping, Cerro Alto Campground is on file at roughly sixteen miles. The water is pleasant and safe. Check who owns the ground before you get out of the car; access is unrecorded.

114 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 65% 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.
