Not every Idaho hot spring survives. Fire, flood, landslides, vandalism and overuse have closed springs across the state over the years, some temporarily and some for good. This collection keeps their records: what each spring was, what happened, and what its status is now. It is part memorial and part warning. The way we treat the springs still open decides how many of them join this list.

White Licks Hot Springs is one of Idaho’s most unusual soaks: two small shacks in the Payette National Forest between Council and Donnelly, each sheltering a single cement pool with its own pair of hot and warm intake pipes — plug and unplug the pipes to dial in your own soaking temperature.
