Great Fountain Geyser
The Great Fountain Geyser is a fountain-type geyser located in the Firehole Lake area of Lower Geyser Basin of Yellowstone National Park, Wyoming. It is the only predictable geyser in the Lower Geyser Basin. I patiently waited about an hour and a half for the eruption. The predicted time for an eruption was between 2:00PM and 6:00PM and it erupted somewhere right around 6:00PM. DSC_4868A
Great Fountain sits in the middle of one of the prettiest sinter formations in the park. The sinter forms a series of terraced concentric reflective pools around the geyser's 16' diameter vent. Even if the geyser isn't erupting, it is worth driving past to see the pools. Its interval range from 9 to 15 hours but its short term average interval is usually stable enough that the eruptions can be predicted to within an hour or two. Great Fountain's maximum height ranges from about 75 feet to over 220 feet. Its duration is usually about one hour but durations of over two hours have been seen. - www.geyserstudy.org/geyser.aspx?pGeyserNo=GREATFOUNTAIN
