Desc: World Natural Heritage USA: Yellowstone National Park: Directed by Norbert Vander. The Yellowstone National Park is the oldest national park in the world. It is home to a landscape with the world's highest concentration of geysers and thermal springs, as well as being famous for its herds of bison that roam the plateaus of the highlands. The herds are often accompanied by wolves, which were reintroduced to the Yellowstone National Park around ten years ago.
