Lava Hot Springs are a system of geothermal mineral springs in Bannock County, Idaho, United States, in the area of the city named after them, Lava Hot Springs.
The springs were historically used by local Bannock and Shoshone Native Americans.[1] In the early 1800s, explorers and fur trappers knew of the hot springs, and Robert Dempsey built a permanent camp nearby. During the 1840s and 50s, travellers headed to California and Oregon were aware of the springs. In 1890, John and Mary Hall, English immigrants homesteaded the site. In 1902, the Shoshone and Bannock peoples ceded the hot springs site and surrounding acreage to the U.S. government.[2]
Lava Hot Springs is located at 42.6194°N -112.0142°W (42.619482, -112.014283),[3] at an elevation of 5020feet above sea level.
The rock content of the spring vents consist of Paleozoic quartzite and younger travertine.[4]
The spring system has a flow of 34 gallons/second / 130 liters/second. The hot mineral water emerges from the ground at 113°F / 45°C.[5] The mineral content of the water includes manganese, sodium, iron, calcium bicarbonate, potassium, magnesium, iron, zinc and fluoride.
