Anderson Springs sits a hundred feet off Hot Springs Road in Lake County, California, about four miles from Cobb. The water on record is hot, right at the top of comfortable soaking temperature. Who owns the ground and what the public may do there are not in the record, which for a spring this close to a road called Hot Springs Road is the question to answer first.

Location

Hot Springs Road is the access, about seventeen hundred feet up in Lake County. This is a wet spot, thirty-two inches of rain in an average year, with only a trace of snow. Owner and designation are both unrecorded, and the road name is the only hint the record gives about what is around the spring. Warm Springs Rec Area, sixteen miles out, is the campground on file.

Winter months rate highest and snow is not a factor. Camp at Warm Springs Rec Area if you need to, a good drive away. The water is at the hot end of soakable. Access is unrecorded; check before you go. No fee appears in the record.

183 milliwatts per square meter of heat flow

That's about 3 times the US average of 65. It's higher than at 98% 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.
