The Giant Geyser ( German Giant Geyser ) is a cone -shaped geyser in the Upper Geyser Basin in Yellowstone National Park in the U.S. state of Wyoming. The Giant Geyser is also named for the Giant Geyser group, which includes The summit and Bijou Geyser and the Mastiff Geyser. In addition, the geyser is eponymous for the Giant Platform, an increased stone plateau on which are the three geysers. The Giant Geyser is mainly for the spectacular fountains, which have up to two meters in diameter, and known around the four -meter-high cone.
History
On September 18, 1870, the eruption of Giant was first observed by the team of the Washburn - Langford - Doane Expedition. Having the Upper Geyser Basin explored and researched and a half days, they called seven geysers in the basin, including the Giant. Nathaniel P. Langford described in 1871 as the Giant:
" The Giant " has a rugged crater of about 3.3 m outer diameter, and an unevenly structured inner diameter of about 2 m. We saw the eruption only once, and it was huge. With nearly 2 m in diameter, the fountain shot for 3 hours in up to 46 m height. The crater also resembles a miniature of the Colosseum.
Eruptions
The eruption takes place very irregular. Time it takes a few days, sometimes a few weeks. In addition, the activity varies considerably from year to year. Occasionally held tremendous eruptions, which are take several hours and up to 80 m high. From 1955, he erupted for several years extremely common, in contrast, found from 1963 to 1987 only six eruptions take place. As of 1997, the Giant was again active and eruptions took place about every four days instead. The most recent active phase began on August 6, 2005 and lasted until 29 April 2008, when then the activity decreased significantly, but not stalled, because on August 26, 2008, an eruption took place again. A total of eleven eruptions took place in 2005, 47 in 2006, 54 in 2007 (which is also the highest number of eruptions of the Giant was in 1955 ) and 15 in 2008. Reasons for the extreme Aktiviätsschwankungen are unknown, but it is assumed that they are based on geothermal energy fluctuations between the Giant and the nearby Grotto Geyser.
The height of the fountain and the relatively frequent and eruptions in recent years, prompted researchers to investigate the Giant often making him one of the most studied geysers in the park. Because of these studies was also derived much about the eruption behavior of geysers, or to learn. Development of steam and bubbling of Geysires can always be in the inactive phase of the Geysires watch, but eruptions are very rare in the inactive periods of the geyser before.
