A tepid spring in Lake County, Hildebrande sits roughly five miles from Soda Bay and only a short way off the road. No owner is on record, and there is nothing on access either. The water lands at the cool end of warm. What it comes out of goes unmentioned.

Location

The nearest road goes unnamed in the record, and the spring is under three hundred feet from it. Modest elevation, wet winters near twenty-eight inches, a bit of snow. For camping, Warm Springs Rec Area is around nineteen miles off. Roadside is the access class, which means you can see it from the car.

Winter is the season on file. Find out who owns the ground first; the record is blank on that. Fees and chemistry are not recorded, and the only campground listed is a long drive. The water will feel lukewarm at best.

Heat Below
165 milliwatts per square meter of heat flow

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.
