History The city is named for the hundreds of natural springs of carbonated water that are located in and around the city. The springs were known to Native Americans, and were a landmark along the Oregon Trail in the middle 19th century. Today the city is also known as the location of the Soda Springs Geyser, which was unleashed in 1934 when town fathers were seeking hot water for a hot pool bathing attraction. They drilled into a chamber of highly pressurized carbon dioxide gas and cold water, and the geyser was released. After running for weeks and flooding the downtown area, it was capped and manually released upon request as a tourist attraction. Currently a timed release valve opens every hour on the hour. Its height and volume have not decreased after many years. Viewing platforms are located at either end of the travertine mound where the geyser erupts. Interpretive signs are located on the platforms explaining this phenomenon. Soda Springs is also the location of one of the Ground Observer Corps sites.
