Great Fountain Geyser is a fountain-type geyser located in the Firehole Lake area of Lower Geyser Basin of Yellowstone. This geyser erupts every 9 to 15 hours and its maximum height ranges from about 75 feet (23 m) to over 220 feet (67 m). Its duration is usually about one hour but durations of over two hours have been seen.

 

While this pattern of behavior is observed most of the time, there are occasional episodes of so-called "wild-phase" activity during which the eruptions are of greatly extended duration and intervals between eruptions may be as long as three days. The geyser is then unpredictable until wild-phase activity ceases and more normal eruptions resume.
