Vigilante Spring is a tepid spring in the Beaverhead National Forest, Madison County, Montana, eighteen miles from Virginia City. Wading is about the most the water allows. Access is open, it is Forest Service land, and it sits almost on the road. Vigilante Cabin is close by, which makes it an easy stop from there.

Location
23 miles from Virginia City, MT

Forest Development Road 163 runs within fourteen feet of the spring, which makes it about as roadside as a spring gets. Elevation is high, snow is heavy at nearly ninety inches, and the climate is wet. Beaverhead National Forest land, no fee on file.

Vigilante Cabin is a mile and a half away. Winter holds the best-months slot on the record, but the snowfall here argues for summer, when a forest road is more likely open and the cabin easier to reach. Access is open. Neither chemistry nor a survey date is on file, and no photo exists.

Heat Below
130 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 80% 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.
