One Shot Mining Co is the name on record for a tepid thermal point in Lake County, about eleven miles from Hidden Valley Lake. The record carries a company name, and nothing else about the site's past. The water measures in the low seventies. No owner or access status is listed.

Location

Five hundred feet or so off an unnamed road at around seventeen hundred feet. Moderately wet, around twenty inches of rain, with snow rare. Camping is far off: Oak Shores Day Use Area, roughly twenty miles.

The record's season is winter. The water is cool for a soak. With no owner listed and a mining name attached, assume the ground may be private until you learn otherwise. No fee on file.

Heat Below
128 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 79% 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.
