A natural spring in Yellowstone National Park, WY
A natural spring near a lake in Yellowstone National Park, Wyoming. Steam rises up behind the spring.
In 1872, Yellowstone became the world’s first national park. The park preserves and protects a stunning variety of flora and fauna, including large mammals such as elk, wolves, bison, moose, and grizzly bears. The park’s most common ecosystem is the subalpine forest. It is famous for its hot springs and geysers. Thousands come to see Old Faithful every year. Yellowstone Lake is located over the Yellowstone Caldera, an enormous supervolcano, and the park’s geothermal features are powered by volcanic activity. From 11,000 years ago to around 200 years ago, the park was home to several different groups of Native Americans.
