Overview

Old Faithful was the first geyser seen by the Washburn-Langford-Doane Expedition when it entered the Upper Geyser Basin on September 18, 1870. It is not the tallest or largest in the park, but its eruptions are predictable: 3,700 to 8,400 gallons of boiling water reach 106 to 185 feet (averaging 145 feet) and last one and a half to five minutes, every 60 to 110 minutes or so. More than a million eruptions have been recorded. Park rangers post predicted times at the visitor center, and boardwalks circle the geyser.
