Soda Springs Geyser

Soda Springs, in Idaho, in the United States, has the only controlled geyser in the world. It was discovered in 1937 when a local man was drilling around to find a hot water source for a swimming pool, and accidentally penetrated an underground chamber 315 feet down. The chamber was filled with pressurised carbon dioxide gas and water that shot out with a lot of energy. However, unlike natural geysers that erupt periodically, the Soda Springs Geyser began spraying continuously. So the geyser was capped and controlled by a timer releasing it every hour on the hour. On windless days, the geyser is reported to reach heights between 100 and 150 feet. There is a Visitor Center nearby and a boardwalk around the geyser and grassy areas with picnic tables and benches to enjoy the day and view the geyser.
