Great Fountain Geyser, Fountain geyser in Lower Geyser Basin, Yellowstone National Park, United States.
The Great Fountain Geyser sends water jets up to 220 feet high through a central vent in a series of recurring bursts lasting one hour.
Since 1883, when photographer W.H. Jackson first documented its eruptions, the Great Fountain Geyser has maintained consistent eruption patterns in Yellowstone National Park.
Scientists discovered the essential bacterium Thermus aquaticus near this geyser, which revolutionized DNA research and molecular biology laboratory procedures worldwide.
Visitors should check eruption predictions at Old Faithful Visitor Center, as the geyser erupts every 9 to 15 hours with a two-hour prediction window.
The geyser creates mineral formations through its fountain-type eruptions, forming stepped terraces and platforms around its central pool over time.

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.
