"Past volcanic activity has shaped the landscape, and the residual geothermal activity has caused the numerous hot bubbling springs that gave it its name. Geothermal activity hundreds of feet below the ground heats water and mixes in carbon dioxide gas. Soda Springs gets its name from the naturally carbonated water. The resulting increased pressure contributes to the number of springs and was the cause of the geyser.""Soda Springs, Idaho in 897 Photographs". UntraveledRoad.com. Retrieved 28 December 2011.
