Old Faithful Geyser, Yellowstone National Park Glass Coaster

"Old Faithful Geyser Preparing to Erupt, Yellowstone National Park, Wyoming" by Catherine Sherman. Steam rises into the sky from Old Faithful Geyser geyser in the vast landscape of Yellowstone National Park, Wyoming. The scene is set against a dramatic sky with patches of clouds and sunlight filtering through. Old Faithful, a cone geyser, was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name. It is one of the most predictable geographical features on Earth, erupting almost every 91 minutes. The geyser, as well as the nearby Old Faithful Inn, is part of the Old Faithful Historic District.
