Yellowstone park spans a neighborhood of three ,468.4 sq mi (8,983 km2) 3 comprising lakes, canyons, rivers, and mountain ranges.Yellowstone Lake is one among the most important high-elevation lakes in North America and is centered over the Yellowstone Caldera, the most important supervolcano on the continent. The caldera is taken into account a dormant volcano. it's erupted with tremendous force several times within the last two million years. Overflow half the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the acreage of Yellowstone. The park is that the centerpiece of the Greater Yellowstone Ecosystem.                                         

How was it made?

Earth’s crust has been smushed, pulled piecemeal, glaciated, eroded, and subordinated to volcanism. All of this geologic exertion formed the mountains, defiles, and mesas that outline the natural wonder that is Yellowstone demesne. While these mountains and defiles may appear to vary little or no during our continuance, they are still largely dynamic and variable. a number of Earth’s most active stormy, hydrothermal, and earthquake systems make this demesne a priceless treasure.
