Boat Box Hot Springs
A single old mining cauldron beside the Salmon River, filled by piped spring water, about three and a half miles from Stanley on Highway 75. It fits three or four people, and a bucket is usually left for adding cold river water. The roadside pull-off holds only two or three cars.
