Castle Geyser
From Free net encyclopedia
Image:Castle Geyser 2.jpg Image:Castle Geyser.jpg Castle Geyser is a geyser in Yellowstone National Park.
The geyser has a 10-12 hour eruption cycle. The geyser erupts hot water for about 20 minutes to a height of 90 feet (27 meters) before changing to a noisy steam phase for 30-40 minutes.Template:Ref
It is also noted for the particularly large sinter deposits that form its cone. These have been likened in appearance to a castle. This appearance led Lieutenant G.C. Doane to name it Castle Geyser in 1870.Template:Ref The geyser is located in the Upper Geyser Basin a short walk from Old Faithful Geyser.
The sinter cone for Castle Geyser was dated to around 1022 using carbon-14 dating. This date is much younger than the presumed age of 5000 to 15000 years. A 3-D laser scan done of the cone shows evidence that this geyser has gone through four to five distinct stages to reach its current configuration.Template:Ref
In November 2002, an earthquake in Denali National Park and Preserve, Alaska caused Castle Geyser, as well as other geysers in Yellowstone, to decrease in eruption frequency.Template:Ref The affected geysers have since returned to their previous pattern.
