Yellowstone National Park is a national park located primarily in the U.S. state of Wyoming, although it also extends into Montana and Idaho. Native Americans have lived in the Yellowstone region for at least 11,000 years.
The region was bypassed during the Lewis and Clark Expedition in the early 19th century. Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km), comprising lakes, canyons, rivers and mountain ranges.
Yellowstone Lake is one of the largest high-altitude lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent.
Yellowstone Park is the largest and most famous megafauna location in the Continental United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in the park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States.
