| The first European to visit the Yellowstone area, John Colter, probably encounters hot springs, leading to the designation "Colter's Hell". Also in 1807, settlers founded the city of Hot Springs, Arkansas, where, in 1830, As a Thompson charged one dollar each for the use of three spring-fed baths in a wooden tub, and the first known commercial use of geothermal energy occurred. | |
