The Yellowstone Caldera is a large volcanic caldera located in Yellowstone National Park, formed by a series of massive volcanic eruptions over the past 2 million years. This caldera is significant in volcanology and geothermal studies for its active geothermal features, potential for future supereruptions, and role in shaping the geology of the region.
