Named hot springs imported from OpenStreetMap that nobody has confirmed yet. They are on the map and in the app, and they get a page here the moment someone reports back from one — not before. Listing every one of them:
A further 13 hot springs in Idaho are on the map with no name of their own — OpenStreetMap records them only as “hot spring”. They are on the map; there is nothing to call them by here.
