Hot Mineral Therapy Pool
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.
Did You Know?
Lava rocks are formed after liquid hot magma erupts from volcanoes, which then cools and hardens on the earth's surface. They are rich in minerals that can be found deep within the earth's core. Lava rocks are a sign of strength and courage, and are said to carry the nurturing properties of Mother Earth. It is thought that these rocks contain the same powerful energy like that of the volcano that created them. Lava rocks are believed to be an excellent aid to healing, especially for those suffering from depression or a lack of energy and vitality.
PLEASE REFRAIN FROM CLIMBING OR ENTERING THE POOL TO AVOID INJURY.
