Yellow-stone National Park, located in the northwest corner of Wyoming and a little into Montana, was established as the world's first national park in 1872. It is huge - 2.1 million acres, which can be divided into five distinct areas - mammoth country, geyser country, lake country, canyon country, and Roosevelt country. Here are some photos of the park.
