Inscription. The hot mineral therapy pool was constructed back in the 1930s. Much like the native Wappo Indians, guests considered the hot mineral therapy pool to have spiritual, healing and rejuvenating properties. Guests would sooth what ailed them by enjoying private baths in custom-made bathing stalls that included a bathtub. A pipe that extended from the capped well to the pool helped to regulate water temperatures.
The walls of the pool are made up of lava rocks indigenous to this area. It is thought that structures like this one were built to protect the water's magical healing qualities.
The walls also served a practical purpose in containing the water, and keeping out garbage and debris from trees and plants. Today, temperatures in the hot mineral therapy pools available in some of the local Calistoga hotels and resorts reach more than 150°F/60°C.
