An eruption from this famous geo-thermal wonder can shoot 3,700 - 8,400 gallons (14,000 - 32,000 l) of boiling water to a height of 106 - 184 feet (30 - 55 m) lasting from 1.5 - 5 minutes.

Old Faithful was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name.

Old Faithful will erupt 65 minutes after an eruption lasting less than 2.5 minutes or 92 minutes after an eruption lasting more than 2.5 minutes.
