Old Faithful, the famous geyser located in Yellowstone National Park, was first documented by members of the Washburn-Langford-Doane Expedition in 1870. The expedition, led by Henry D. Washburn, was among the first to explore the geothermal features of the area. While Native Americans were aware of the geyser long before, this expedition marked its introduction to the wider public and scientific community. The geyser was named "Old Faithful" due to its regular and predictable eruptions.
