1Yellowstone National Park in the western United States was the world's first national park.
2Established in 1872, it is famous for its geothermal activity and wild animals.
3It includes beautiful mountains, deep canyons, lakes and rivers.
4Yellowstone is still one of the largest national parks in the U.S.
5It takes up almost 9,000 square kilometers.
6Most of the park lies within the western state of Wyoming.
7The park is unusual because of what lies underneath it.
8It sits on top of an ancient super volcano, known as the Yellowstone Caldera.
9The caldera remains an active volcano.
10A lake of hot liquid rock is about six kilometers under the park.
11Experts say this lake is under huge amounts of pressure.
12The pressure and heat cause geysers to shoot hot water out of the ground and mud to boil at Yellowstone.
13The park is home to more than 300 geysers.
14There are more geysers and hot springs in Yellowstone than any other place on Earth.
15"Old Faithful" is the name of the park's most famous geyser because it erupts about every 90 minutes.
16Yellowstone is on a high plateau with an average height of 2,400 meters above sea level.
17This makes the weather very cold in winter, with January temperatures averaging between -18 degrees and -7 degrees Celsius.
18However, some areas of the park remain open to visitors throughout the year.
19Yellowstone Canyon is about 365 meters deep.
20The Yellowstone River runs through it and drops 93 meters in the Lower Falls.
21Visitors can walk on a path that brings them very close to the top of the falls.
22There, they can see and hear the powerful falls.
23In summer of 1988, forest fires burned large areas of the park.
24Most of those areas are now covered with plants and young trees.
25Yellowstone is home to the largest group of wild animals in the lower 48 United States.
26These include bison, grizzly bear, elk, deer, moose, fox, beaver, coyote and wolves.
27In 2024, park officials estimated the bison population to be about 4,500 animals.
28That makes it the largest group of wild bison in the world.
29There is still a wild west in America...and its name is Yellowstone.
