Hot springs in the United States

Hot springs (also known as thermal springs, geothermal springs, and hydrothermal springs) exist in many areas throughout 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.[1]

Many hot springs are natural rock soaking pools that are only accessible on foot or horseback, while others are developed into resort spas. The purpose of this list is to focus on the thermal springs themselves: their history, geography, geology and water profile. This list primarily covers the more undeveloped and/or historical hot springs.

A helpful guide to 1664 hot springs can be found on the NOAA Thermal Springs List for the United States,[2] or in book and map form.[3] The same list with added notes and links can be found on the USA Hotsprings Database.[4]
