Old Faithful
This landmark is the Old Faithful. It is a cone geyser in Yellowstone National Park. It has erupted almost every 44 minutes to two hours since 2000. Explorers in the Washburn-Langford-Doane Expedition gave the geyser its name in 1870. One member, Nathanial P. Langford, wrote in his account that they chose “Old Faithful” because the geyser spouted at regular intervals.
