Yellowstone: The World's First National Park

Home to some of the most majestic scenery in the United States, Yellowstone National Park contains nearly 9,000 square miles of forests, geysers and other natural wonders. This documentary explores the park's history and its most well-known sites -- including Yellowstone Falls and Old Faithful -- and includes a short film on the wolves that call the park home, as well as clips from the 1930s drama "Yellowstone."
