Fumarole
This entry is a fumarole, a steam vent, about two miles from Clearlake in Lake County, ten feet off Oak Street. There is no measured water temperature in our data, only a note that it runs hot, and there is no pool. Nothing here is for soaking. It is a patch of geothermal ground on the edge of town.
Edge of Clearlake, with the vent right at the roadside on Oak Street. The climate is mild, twenty five inches of rain, a dusting of snow some winters. Ownership and access are both blank in our data. Little Stony is the nearest campground on file and it is over twenty miles away.
There is no best month listed and no temperature, so there is nothing to plan a soak around. If you are curious, it is a roadside stop. Access is not on record, so assume nothing about being able to walk up to it. No fee information. No camping nearby.
Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Fumarole.
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.

That's about 3 times the US average of 65. It's higher than at 99% 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.
