In the early 1800s, explorers in north america came back from the west with stories about a strange land with boiling mud, streaming lakes, and trees made of stones.
The stories seemed incredible but they were true.
The explorers had discovered Yellowstone.
In 1892, it became America's and the world's first National Park.
Today, more than two million people visit Yellowstone National Park every year.
One of the most popular sights is it's famous geyser called Old Faithful, which erupts every 90 minutes, day and night.
The park has more than 300other geysers more than 60% of all the geysers in the world.
There are also pools of hot mud, and hot blue lakes with stream above them.
Because Yellowstone is full of warm places in the winter, it is the homeofmany kinds of animals and plants.
Visitors to the park have the opportunity to see wolves, bears, and , if they are lucky, a mountain lion.
Just be careful where you walk: every year, some visitors are burned by hot mud or water.
