When you think about Yellowstone, it is probably the bubbling hot springs and the geysers that come to mind. Old Faithful, the best known, erupts every 90 minutes (although eruptions can come closer) spouting between 3,700 and 4,500 gallons of hot water and steam 145 feet up into the air.

While the Old Faithful geyser is one of the classic scenes in all the United States, it is not on every American's "must see" list. Yet it really should be!
