JessiccaFact: Old Faithful
December 3rd 2006 09:57
Old Faithful is the most famous geyser in the world, but not the highest or most regular. Located in Yellowstone National Park, Wyoming, Old Faithful reaches heights of 106 to 184 feet.
Eruption intervals range from 65 to 92 minutes with 91 minutes being the average, and each eruption lasts from 90 seconds to 5 minutes. Old Faithful erupts 15 times per day and spews out between 3,700 and 8,400 gallons of hot water.
It was named in 1879 by members of the Washburn Expedition for the regularity of its eruptions. The Steamboat Geyser is the tallest geyser in the world and is also located in Yellowstone National Park. It can reach a height of over 300 feet, but its eruptions are rare and unpredictable.
