Imperial Geyser doesn't garner the acclaim of Yellowstone National Park's more renowned front-country geysers, such as Old Faithful, Grand or Castle, but it's worth a visit.

Located off the Fairy Falls Trail, the geyser was "discovered" in 1927, named through a contest involving the National Editorial Association, and was thought to have one of the greatest discharges of water per eruption at roughly 878,000 gallons.

Though Imperial went dormant from September 1929 until August 1966, it's still spouting these days, though probably not much more than 25-30 feet in height.
