Yellowstone

Yellowstone is no ordinary wilderness – a lost world of vast plains and endless forests defended on all sides by towering mountains, home to America’s last great Bison herds, and the realm of the wolf. It is also the most extensive thermal area on Earth with more than 10,000 boiling springs, fumaroles, and bubbling mud pots, plus more Geysers than the rest of the world put together. In a land of beauty and peril, the dramatic lives and fortunes of its animals are inexorably bound together.
