Crested Pool, in the Upper Geyser Basin of Yellowstone National Park, lies just steps away from Castle Geyser. Crested Pool extends 42 feet deep and is constantly superheated, achieving temperatures to at least 237Â°F. Crested Pool is always at least boiling and occasionally domes to heights of 10 feet. In 1970 a young visitor, not realizing how hot the water in Crested Pool was, ran into the stream and pool and was killed. A railing now keeps visitors back.
Crested Pool is a blue, superheated pool. Unfortunately, it has claimed a life. It reaches a overflowing boiling state every few minutes, then subsides a bit before building to a boil and overflow again. Upper Geyser Basin.
