Pincock Hot Springs, also written up as Green Canyon Hot Springs, is in Fremont County around twenty miles from Ashton. The USGS sampled it in 1977 and found it hot, a few degrees over what most people can sit in comfortably, with water close to neutral. Neither an owner nor an access status appears on file.

Location

The walk in from the nearest road is about a fifth of a mile. Which road that is, the record does not say. The spring sits fairly high, in country that averages in the low forties through the year and collects something like six and a half feet of snow. Precipitation is middling.

Midwinter gets the nod as the best time. Table Rock is the campground on file, roughly thirteen miles away. That temperature reading is almost fifty years old, so expect it to have drifted. What was measured then was hot enough to want cooling. Since ownership is unknown, check locally before you plan a soak.

Heat Below
118 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 70% 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.
