Yellowstone National Park is America's first national park, established in 1872. Yellowstone extends through Wyoming, Montana, and Idaho.
The park's name is derived from the Yellowstone River, which runs through the park. It's unclear if the name first referred to the sulfurous yellow rocks below the falls of the Grand Canyon of the Yellowstone River or to the sandstone bluffs that border its shores.
