In 1872, the Congress of the United States created the first national park in the world. Yellowstone National Park occupies the homonym plateau in the northwestern US. The view is breathtaking and incredibly varied. There are canyons, waterfalls, mesas covered by pastures, and forests. IT has the largest geyser field in the world. The muddy volcanoes are a spectacular phenomenon. They are the eruption of gases released by hydrocarbons layers deep beneath, which train water and mud on their way to the earth's surface.
The Amethyst Mountain in the Northwestern section of Yellowstone is a vertical section of 600m in the rock, offering the occasion to see 12 successive fossil forests, covered by volcanic dust. There are also three big rivers: Missouri, Snake River, and Yellowstone River. Yellowstone River also forms an impressive canyon. It is an awesome view. There are also many different animals: Elks, Bisons, Black bears, wolves, coyotes, bald eagles, and pelicans. The waters are populated with trout.
