Out in the Gravelly Range country of Madison County, Montana, Andersons Pasture Springs is a warm spring a long way from anywhere. Virginia City is the closest town anyone lists, about forty miles off. The water comes up tepid, enough to register on your hand and nowhere near a soak. No owner appears, and access has never been settled. Until somebody learns more it stays a thermal point on a map.

Location

The spring sits at high elevation, with Gravelly Range Road passing about half a mile away. Reaching it means a short walk off that road. Winters here are long and snowy, the kind that bury a place for months, and the year is reasonably wet by Montana standards. Average temperatures stay cold.

The months flagged as best on the record are December through February, which with this much snow means the road itself may be a problem. Most people would find summer easier. West Fork Cabin, around seven miles away, is the camp on file. The temperature comes from a 1977 survey, so it may have changed. Check land status before you go.

Heat Below
115 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 67% 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.
