Yellowstone national park
Yellowstone National Park was the first national park in the world. It was created on March 1, 1872 when United States President Ulysses S. Grant signed a law to create it.
Yellowstone National Park is famous for its geysers and hot springs. The Park contains about half the world's geysers. It also is a home for grizzly bears, wolves, bison and elk. Many tourists visit the park each year to see the geysers and animals there.
Most of the park (96%) is in Wyoming; it is about 3,500 sq miles in extent, bigger than Rhode Island or Delaware.
