Yellowstone National Park covers an area of 3,468.4 square miles (8,983 square kilometers) and consists of lakes, canyons, rivers and mountains. Yellowstone lake is one of the largest high-altitude lakes in North America, located in the center of Yellowstone crater, the largest super volcano in the continent. Crater is considered as an active volcano. In the past 2 million years, it broke out several times with great power. Due to persistent volcanic activity, half of the geothermal features in the world are located in Yellowstone National Park. Lava flows and rocks generated by volcanic eruptions cover most of the land in Yellowstone National Park. The park is the core of the Great Yellowstone ecosystem and the largest and almost complete ecosystem in the northern temperate zone of the earth.
Yellowstone National Park (English: Yellowstone National Park) is the first national park in the world, established at 1872. Yellowstone National Park is located in the northwest corner of Wyoming in the midwest of the United States, extending northwest to Idaho and Montana, covering an area of 7,988 square kilometers. This area was originally a sacred place for Indians, but it became the earliest national park in the world due to the excavation of American explorers Lewis and Clark. 1978 is listed as a world natural heritage.
The height of the park rises from 53 14 feet (1.620 meters) at the northern entrance (Gardner, Montana) to 1 1.358 feet (3,462 meters) at Eagle Peak, the highest point in the southeast of the park. There are the largest geysers in the world in the vast natural forest of Huangshi National Park, where more than half of the geysers in the world are located. These geothermal wonders prove the existence of the largest active volcano in the world. Yellowstone National Park takes the bear as its symbol. There are about 200 black bears and 100 grizzly bears in the park. Besides, there are all kinds of wild animals in the Great Yellowstone Ecosphere of this national park, including bison, pronghorn, moose, red deer, white-tailed deer, bighorn sheep, coyotes, grey wolves, otters and so on.
