Upper Geyser Basin, Old Faithful area · Yellowstone National Park, WY
Old Faithful is a cone geyser in Yellowstone's Upper Geyser Basin, named in 1870 by the Washburn-Langford-Doane Expedition. Eruptions reach 106 to more than 180 feet and last 1.5 to 5 minutes, and rangers post the next predicted time at the Old Faithful Visitor Education Center. Boardwalks lead on through a basin holding roughly 150 geysers within one square mile. Next door, the 1904 Old Faithful Inn has a 65-foot lobby ceiling and a massive rhyolite fireplace.
