Geysers! Geysers! It was September 18, 1870 when a member of the Washburn, Langford, Doane Survey Expedition spotted a spectacular column of water spewing forth in the near distance from their party, and cried out "Geysers! Geysers!" Observing a pattern of regular activity throughout the day, they named the geyser Old Faithful. It was the beginning of generations of awe-inspired visitors to the land that became Yellowstone, America's first national park. The abundant geothermal features of the park—geysers, hot springs, fumaroles, and mud pots—owe their existence to Yellowstone Volcano. The volcano's most recent eruptions, 640,000 years ago, formed Yellowstone Caldera, 35 miles wide and 45 miles long. The giant caldera lies in the central part of the park.
