Yellowstone Lake is the largest mountain lake in North America and its southern half is the Yellowstone Caldera, the continent’s largest supervolcano, considered an active volcano. There is evidence that at least in the last millions of years it has erupted with tremendous force on several occasions. At least half of the world’s geothermal attractions are located in Yellowstone, caused by its strong and consistent volcanic activity. The lava flows and rocks emitted by volcanic eruptions cover most of the Yellowstone area.
