France. The Geyser On November 30, 1937, a well-drilling operation while attempting to build a natural hot springs swimming pool was surprised when it unintentionally released Soda Springs’s famous captive geyser, which surprised everyone by shooting 100 feet into the air. It has been capped, and a timer activates it once every hour on the hour. The water is about 70 degrees Fahrenheit. There is now a park and a visitor center at the site. In addition to its captive geyser, Soda Springs has an industrial lava flow from the dumping of molten rock left over from Bayer's phosphate mining and manufacturing process one mile north of the town.
