On Wikipedia

Fountain Geyser is a geyser in the Lower Geyser Basin of Yellowstone National Park in the United States. Fountain is the dominant member of a group of geysers at the Fountain Paint Pots thermal area. Morning Geyser, which erupts from a vent close to Fountain's, is larger, but is inactive during most years. Fountain, by contrast, is usually active. It is a fountain-type geyser that erupts jets ranging in height up to 80 feet (24 m) or more, with most eruptions containing at least a few bursts that reach 40 to 50 feet. Intervals between eruptions vary from year to year but are commonly about 6 hours, with occasional longer intervals of 11 to 12 hours. Durations of eruptions are typically about 30 minutes. On occasion Fountain departs from its usual behavior and enters so-called "wild-phase"…
