Monterey County has this unnamed hot spring a dozen or so miles from Carmel Valley Village, where the recorded temperature is 114 degrees. Hot, above what most people tolerate for long. It sits low, a couple hundred feet up from the sea. Neither the landowner nor the public access status is on file, and the record holds no photograph.

Location

The record calls it a short walk, about four tenths of a mile, and does not name the road. No snow falls here and precipitation runs about twenty-eight inches a year. Year-round the mean temperature on record sits in the high fifties, mild all told. Neither land unit nor designation appears on record.

The months on file are late winter into early March. White Oaks Campground is about fifteen miles off. At 114 degrees the water can scald given time; test it and do not sit in the hottest part. Ownership is unrecorded, so establish you are allowed there. No fee on file.

Heat Below
100 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 48% 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.
