Location

Hot Creek Hatchery Road is the access, and the springs are a couple of hundred feet from it, so this counts as roadside. Forest Service land. You are at close to seven thousand feet on the east side of the Sierra, where a typical winter lays down seven feet of snow and the remaining months stay fairly dry.

The record puts the best visits in the winter months, December into February. Convict Lake Campground is four miles away. Do not touch the water; it will scald you. The chemistry on file is from a 1997 sample with a high pH, and a photo exists in the record. The access listing says Open, though the file does not say how recent that is, so check with the Forest Service for closures.

133 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 84% 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.
