DescriptionLava Hot Springs was named for the mineral springs that boil out of lava rocks at the base of massive cliffs along the Portneuf River. Geologists believe that the pools have remained at the same temperature—110 F—for 50 million years. Lava Hot Springs is a popular health and pleasure resort offering hiking, bicycling, tubing, ziplining and swimming.
For centuries the Shoshone and Bannock Indians regarded the springs as a neutral site. But the tribes camp was disrupted during the 19th century when the springs were discovered by Oregon-bound travelers and Utah pioneers who founded a settlement called Dempsey. By 1902 the Native Americans had ceded their rights to the springs, selling the land to the U.S. government, which in turn gave the area to the state.
