Castle Geyser eruption steam Upper Geyser Basin cone geyser Old Faithfull Yellowstone

Location: Yellowstone National Park. Wyoming. US

This picture corresponds to Castle Geyser, one of the most famous geysers in Yellowstone. When the geyser was given this name in 1870, the top edges of the structure resembled the typical profile of a castle.

This is one of geysers that you shouldn't miss in Upper Geyser Basin. The Castle Geyser has a 10 to 12 hour eruption cycle and it is one of the most spectacular and enjoyable eruptions among all the geysers in Yellowstone. The geyser erupts hot water for about 20 minutes in a vertical column that reaches a height of 90 feet (27 m) before changing to a steam phase that issues for 30 to 40 minutes.

As in most geysers that have a steam phase, the change from water to steam is gradual and an exact time for the change can rarely be noted. In this case, the steam phase is particularly noisy. I actually enjoy this much more than Old Faithful because you can get much closer and you can really feel the power of the steam and boiling water coming out the vents.
