Giant Geyser, Cone geyser in Upper Geyser Basin, Yellowstone National Park, US
Giant Geyser reaches heights of 250 feet during eruptions, releasing steam and water from a 12-foot-tall cone structure in the geothermal landscape.
The Washburn-Langford-Doane Expedition first documented and named Giant Geyser on September 18, 1870, during their exploration of the Yellowstone region.
Native American tribes recognized the geothermal features of Yellowstone, including Giant Geyser, as sacred places within their ancestral territories.
Visitors can observe Giant Geyser from designated viewing areas along marked trails, maintaining a safe distance from the high-temperature geothermal features.
Between 1955 and 1963, Giant Geyser entered a period of dormancy with only six recorded eruptions through 1987, demonstrating its irregular behavior patterns.

Geysers represent Earth's geological forces through their regular water eruptions. From Yellowstone to Kamchatka, these thermal springs display our planet's underground activity. The fountains reach heights of several meters and generate steam columns at regular intervals.
