Out in Valley County, about nineteen miles from McCall, Stinky Warm Spring comes out tepid. The warm half of the name checks out, barely. The one reading on file puts the water below body temperature, and it was taken in June 1980. Mineral testing that day found calcium, magnesium, sodium, sulfate and chloride, and the water runs mildly alkaline.

Location

The spring lies within a few hundred feet of a road, though the road itself is not named in the record, and the owner of the ground is not identified either. Elevation is modest for Idaho, a bit over three thousand feet, yet this corner of the state gets heavy snow, twelve or thirteen feet of it most winters, and a wet year overall. No public access status has been filed.

December through February show up as the recommended months, so plan on a snowy drive in. Grouse Campground is the closest place to camp on file, a little under nine miles off. Water this cool poses no burn risk. What you cannot confirm from here is whether you are allowed on the property, so ask locally before you go. The chemistry and temperature are from 1980.

Heat Below
89 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 30% 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.
