Old Faithful Geyser is one of the most famous geysers in the world, known for its regular eruptions. It was named in 1870 for its reliability in spewing hot water and steam at intervals of 60 to 110 minutes, reaching heights of 100 to 180 feet. Each eruption lasts about 1.5 to 5 minutes, discharging up to 8,400 gallons of water. Old Faithful is fueled by geothermal activity from the Yellowstone Caldera, a supervolcano, and has erupted more than a million times since the park's founding.
