Soda Springs, Idaho

Soda Springs, Idaho has made a name for itself by turning a small natural hot spring in the area into a full fledged, albeit man made, geyser. Some inspired entrepreneurs tried to market soda water (under the brand name Idan-ha) by drilling for carbon dioxide from a spring near town, kegging the gas, and carbonating local water in the bottle. This turned out to be a bad idea, as the gas was impregnated with a sulfur smell, which made any water all but unbearable.

Said entrepreneurs then decided to make the best of a bad situation, and to turn their fledgling seltzer company into a hot springs bath house. Expanding their drill hole, they hit hot water which shot out of the bore a la There Will Be Blood. Once they contained their gusher, the town now had a fully functional geyser that they could throw on at the turn of a valve. The joke in Yellowstone is that tourists ask where the pump house is for Old Faithful. Here, it is located several feet from the pipe that emits the geyser water every hour, on the hour.
