Clouds of steam and a stream of boiling water erupt from Old Faithful, the most famous of more than 500 active geysers found in Yellowstone National Park, which straddles the states of Wyoming, Montana, and Idaho in the USA. The time between eruptions of Old Faithful ranges from 60 to110 minutes, and its spout can vary in height from 106 to184 feet (32–56 meters). Eruptions normally last between to 5 minutes. Geysers are among the park's 10,000 hydrothermal wonders that include multicolored hot springs, mud pots and fumaroles (steam vents).
