Pistol Creek Hot Springs is a hike-in spring in Boise National Forest, Valley County, nearly three miles from the road and better than forty miles from Cascade. The water is hot, a bit above what most people will sit in without mixing. Open access. The water tested strongly alkaline when it was sampled.

Location

Mountain country with over ten feet of snow per winter and a wet climate. A hike of nearly three miles separates the source from the nearest road, which is unnamed in the record. Forest Service land, standard National Forest designation. The trail and its condition are not described anywhere in the record.

Winter carries the best-months label, but the snow load argues for going when the route is clear. Boundary Creek Campground is the closest on file, about fourteen miles. No fee on file. The source water needs a test before you commit, and the figure on record is from an old survey.

Heat Below
127 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 77% 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.
