## About Vulcan Hot Springs

Vulcan Hot Springs surfaces close to boiling. The source is nowhere near safe to touch, let alone enter. It sits in Boise National Forest off Stolle Meadows Road, about eighteen miles from Cascade in Valley County, open to the public according to the Forest Service. Whatever soaking happens here happens only where the water has had a long way to cool, and the record says nothing about pools.

A walk of a bit over half a mile from Stolle Meadows Road brings you to the springs. The ground is national forest at around fifty-five hundred feet, with sixteen feet of snow over a typical winter and a wet climate through the year.

The months singled out on record run December into February, and at this elevation that means a snowy half-mile in. Stolle Meadows Cabin is the nearest listed overnight spot, about two miles away. The source will scald instantly; keep well clear of the vents and test any cooled water carefully before wading. The temperature on record is from June 1980.
