This is a dynamic list of hot springs in the United States. The Western states in particular are known for their thermal springs: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming; but there are interesting hot springs in other states throughout the country. Indigenous peoples' use of thermal springs can be traced back 10,000 years, per archaeological evidence of human use and settlement by Paleo-Indians. These geothermal resources provided warmth, healing mineral water, and cleansing. Hot springs are considered sacred by several Indigenous cultures, and along with sweat lodges have been used for ceremonial purposes. Since ancient times, humans have used hot springs, public baths and thermal medicine for therapeutic effects. Bathin
