00:00Castle Geyser had a unique appearance, is a tall geyserite cone structure located in
00:07Yellowstone National Park, Upper Geyser Basin. It is known for its exceptionally substantial
00:14deposits of geyserite cenotaphs, which form a cone. These deposits have been related to
00:21castles in terms of looks. The Castle Geyser Cone dates back thousands of years, even older
00:28platforms. Castle Geyser is the oldest of all geysers in the basin, and its eruption
00:34pattern has changed significantly throughout its history. The top edges of the geysers
00:40look like the typical profile associated with the modern concept of a castle, with the appearance
00:46of several turrets, and in particular with the granulation along the top edges of what
00:52appear to be its towers. The layers of material produced in subsequent eruptions cause the
00:59cone forms to vary over time. The eruption cycle of the Castle Geyser lasts 16-17 hours,
01:07before transitioning to a piercing steam phase that lasts for 30-40 minutes. The geyser shoots
01:14hot water for roughly 20 minutes in a vertical column that reaches a height of 80-90 feet.
01:21The water is unreachable for scientific measure because of the height of the cone and the
01:26quantity of brittle cinder. Carbon-14 dating was used to date Castle Geyser
01:32Cenotaph Cone to around 1022. This date is far younger than the previously estimated
01:39age of 5,000-15,000 years. A 3D laser scan of the cone reveals that the geyser erupted
01:46through four to five separate stages before reaching its current structure.
01:51In November 2002, the Denali earthquake in Alaska's Denali National Park reduced the
01:57frequency of eruptions at Castle Geyser and other Yellowstone geysers. However,
02:03the afflicted geysers have since resumed their regular patterns. Compared to the
02:09cenotaph steps on the east side of Castle Geyser, the western side seems smoother.
02:15According to the legends, visitors ripped off the thermophile mats that were once on the cone,
02:21irreversibly harming its structure. The water is currently flowing down the east side,
02:27and no thermophiles are in sight. A vent beside it regularly discharges massive
02:33streams of boiling water, and while the geyser is active, the water in this vent heats and
02:39bubbles violently. If you like this video, please comment, share and subscribe. Thank you very much.
