Kendall Warm Spring is a warm spring in Bridger National Forest, Sublette County, Wyoming, about thirty miles from Pinedale off the Green River Lakes Road. Warm is accurate: the record gives the mid eighties, pleasant to the hand, cool for a soak. Forest Service land, access open, and a campground under two miles away.

Location

High, close to 7,800 feet, in country that sees well over a dozen feet of snow in a season and about two and a half feet of precipitation. The Green River Lakes Road passes within a tenth of a mile. Whiskey Grove Campground is the camping on record, two miles away.

Whiskey Grove is close, which is the practical draw. Winter is the season on file; the road will be under snow then. Water chemistry is from a 1966 sample, mildly alkaline. No fee listed. Temperature is harmless.

Heat Below
112 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 63% 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.
