Yellowstone's Old Faithful Geyser
Old Faithful is a cone geyser located in Wyoming, in Yellowstone National Park in the United States. Old Faithful was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name. The geyser, as well as the nearby Old Faithful Inn, is part of the Old Faithful Historic District.
