YELLOWSTONE NATIONAL PARK
Yellowstone National Park is primarily located in the state of Wyoming extending only partly into the states of Montana and Idaho. The park was established in 1872 and is the first National Park of the United States. Yellowstone is known for its wildlife and its many geothermal features, including Old Faithful Geyser, one of the most popular tourist attractions within the park. The park is 3,468 square miles in area and is comprised of lakes, canyons, rivers and mountain ranges. The park encompasses many types of ecosytems but the subalpine ecosystem is most dominant.
Yellowstone Lake is one of the largest high-altitude lakes in North America. The lake is centered over the Yellowstone Caldera and is considered an active volcano. This super-volcano is the largest of its kind on the continent.
Grizzly bears, wolves, and free-ranging herds of bison and elk live in the park as well as many other species of wildlife.
