Crested Pool


Crested Pool is 42 feet deep and is constantly superheated. With temperatures above 199 degrees F (93°C), it is almost constantly boiling, sometimes to 8 feet or more (2.4 m). The extreme heat prevents most bacterial growth, resulting in exceptionally blue water. Boiling is particularly active along the intricate sinter formation circling the spring, the "crested" edge.
