Dangerously Hot, Not Safe for Soaking

Growler Hot Spring reaches 203°F, far above safe soaking levels. Contact with this water will cause severe burns. Look for cooled downstream pools or view from a safe distance only.

Growler Hot Spring runs close to boiling. It sits in Plumas County about sixteen miles from Chester, and the water is scalding, far past anything a person could sit in. The record carries no note on who owns the land or on public access, and no land unit is given. A photo exists.

Location

The walk in is short, a few hundred feet off a road the record leaves unnamed. Elevation puts it shy of a mile up, and the climate numbers are wet: heavy snow most winters and plenty of rain the rest of the year. Without a land owner or unit in the row, you cannot tell from here if this is public ground.

Hole-in-the-Ground Campground is roughly six miles away. The months listed as best run December through February, which sits oddly beside the snowfall total, so check road conditions before trusting it. Water this hot will burn skin on contact. Keep dogs and children back from the source. Public access is unrecorded.

Heat Below
108 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 58% 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.
