Castle Geyser
From Biocrawler, the free encyclopedia.
Castle Geyser is a notable geyser in Yellowstone National Park. It usually erupts every 13 hours, but is often unpredictable. The geyser erupts hot water in liquid for a while before changing to a steam phase.
It is also noted for the particularly large sinter deposits that form its cone. These have been likened in appearance to a castle. The geyser is located in the Upper Geyser Basin a short walk from Old Faithful Geyser.
