A warm spring, and only warm. Boulder Creek Spring in Valley County measures in the low eighties, which passes for bath temperature on a summer day and does nothing for you in the cold. It sits off Boulder Creek Road about 22 miles from McCall. There is no record of an owner and none of whether the public may go. A photo exists, which is more than most of the small Idaho springs can claim.

Location

The spring is a few dozen feet off the road, close enough that you would see it from the driver's seat if you knew where to look. Elevation is low by Idaho standards, about three thousand feet, but the snow still comes in hard, over twelve feet in a normal winter. Annual precipitation is high too. Expect a wet green valley with a muddy shoulder season.

The winter months get the best-time nod on file, yet with this much snow the road may be the limiting factor, so ask locally. Grouse Campground is the nearest developed camping, a little under twelve miles away. The water chemistry, which leans very alkaline, was sampled in 1980 and has not been updated since. Landownership and access both need checking.

Heat Below
92 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 34% 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.
