Indian Creek Hot Spring is a backcountry source in Custer County, Boise National Forest, nearly fifty miles from Challis. Where it surfaces the water is close to boiling. That rules out soaking at the source and makes it a hazard. Access is open, and reaching it means a hike of close to four miles from the nearest road.

Location

Nothing about this is roadside. The closest road is almost four miles off, name unrecorded, and the spring sits at mid elevation in country that gets over ten feet of snow a year. National Forest land without a wilderness designation in our data. Johnson Creek Guard Station, nineteen miles distant, is the nearest camping our data has.

Our climate data favors midwinter for dryness, but with over ten feet of snow a year the route will be buried in those months. Water this hot will scald you instantly; do not touch it without checking. The 1979 survey is the only chemistry we have. No fee listed.

Heat Below
121 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 72% 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.
