The city is named for the hundreds of natural springs of carbonated water that are located in and around the city.[5] The springs were known to Native Americans, and were a landmark along the Oregon Trail in the middle 19th century. The city is also the location of the Soda Springs Geyser, which was unleashed in 1937 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 erupted. After running for weeks and flooding the downtown area it was capped and then manually released, at first upon request, as a tourist attraction. More recently a timed release valve opens every hour on the hour. The geyser's height and volume have not decreased in the decades since. Viewing platforms are located at either end of the travertine mound where the geyser erupts. Interpretive signs are located on the platforms explaining the phenomenon.[6]
Soda Springs is also the location of one of the Ground Observer Corps sites.
According to the United States Census Bureau, the city has a total area of 4.59 square miles (11.89 km2), of which, 4.54 square miles (11.76 km2) is land and 0.05 square miles (0.13 km2) is water.[7]
