Water at Morgan Hot Spring is hot enough to cook with. The spring is in Plumas County, sixteen miles or so from Chester. Scalding, with no owner on record and no access status. No photo either. The interest is geological; nobody soaks in water like this at the source, and the record has no word on any cooled pool nearby.

Location

A tenth of a mile on foot from the nearest road, which is unnamed here. Elevation is under five thousand feet in wet mountain country where snow piles high in winter. Hole-in-the-Ground, the campground listed, is between five and six miles away. Land unit is blank, and so is owner, which leaves the question of who controls the ground open.

Winter rates as best in the record, and the snowfall makes that doubtful; confirm access by road before counting on it. The water scalds. Keep hands and dogs out. Hole-in-the-Ground is the camping option on file. Nobody is listed as owner, so look for signs.

Heat Below
110 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 60% 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.
