Grizzly Spring
Grizzly Spring is a barely warm spring in Lake County, eight miles out of Clearlake. The temperature on file is below seventy, so this is a cool mineral seep more than a soak. It sits next to a road. Ownership and access are not on record.
Eighty-odd feet off a road with no name on file. Modest elevation in the Clear Lake hills, rain near twenty-two inches yearly, snow a trace, temperatures averaging in the low sixties. Little Stony is the only camp on record, twenty miles off. Roadside access, so the walk is nothing.
Midwinter is listed as best. Since access and ownership are blank, confirm you are allowed there before stopping. Fees and chemistry are both unrecorded. The water will feel cool; it does not reach the warmth of a bath, and nothing on file says what minerals it carries. Treat the temperature as a survey figure, with no date attached.
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 Grizzly Spring.

That's about 2½ times the US average of 65. It's higher than at 96% 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.
