OLD FAITHFUL INN AND GEYSER

Old Faithful Inn and Geyser are in the upper Geyser Basin of Yellowstone where the largest and finest geysers in the world are gathered within a space of a mile. About Old Faithful is another of the Park community centers and supply points with stores, camps, museum, bath house, etc.

— The exterior look of the Inn has changed little over the years. The geyser is predictable to a range of about 15 minutes, averaging an eruption every 74 minutes.
