Yellowstone Plateau

The Yellowstone Plateau is a vast upland area in the western-central United States, primarily located within Yellowstone National Park in Wyoming. This plateau, with an average elevation of about 7,875 feet (2,400 meters), is characterized by its broad, relatively flat surface, though it is bordered by mountain ranges and dissected by rivers and canyons.12

The plateau sits atop a supervolcano that has experienced three massive eruptions, the most recent occurring approximately 640,000 years ago. These eruptions created enormous calderas, the largest of which is the Yellowstone Caldera, measuring about 30 by 45 miles (50 by 70 km). The region is geologically active, with numerous hydrothermal features like geysers and hot springs, as well as frequent seismic activity. The park itself was established in 1872 and is renowned for its unique geological formations and abundant wildlife.34156
