Toiyabe National Forest holds this unnamed thermal point in Douglas County, about nine miles out of Gardnerville Ranchos. The reading on record is 149 degrees, scalding at the source. Nobody should step into water that hot without first finding where it has cooled. Forest Service land, access listed as open.

Location

A road listed on file as Barney Riley comes within a couple tenths of a mile; the record calls that a short walk. The spring sits a little above five thousand feet. Winters are heavy here. Close to ten feet of snow falls most years, and annual precipitation is a bit over two feet.

Expect snow underfoot; the record's months are winter, December through February, so plan the drive accordingly. Indian Creek Campground is four miles or so distant. Treat the source with caution: 149 degree water burns almost instantly. Test before touching. No fee shows up on the record, and no second name from OpenStreetMap either.

Heat Below
114 milliwatts per square meter of heat flow

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