## About Unnamed thermal spring

Off Old Long Valley Road about five miles from Clearlake, an unnamed spring the record puts at 81 degrees. Lukewarm, in other words. It sits in Lake County at low elevation, and the record has nothing on ownership or on public access. No photograph or chemistry is on file, and OpenStreetMap has nothing to add.

The spring is a few hundred feet from Old Long Valley Road, which makes it roadside by the record's classes. Elevation is about fourteen hundred feet. Around twenty-three inches of precipitation falls in a year, with snow a few inches at most. The average temperature on file is in the low sixties.

Winter is the time on file. Little Stony campground is eighteen miles or so away. With ownership unrecorded, check before you visit. No fee noted. An 81 degree reading means a cold day will feel cold in the water, so pick your weather. Clearlake is close enough that asking around there is the sensible first step.
