A natural history portrait of a year in Yellowstone, following the fortunes of America's wildlife icons as they face the challenges of one of the most extraordinary wildernesses on Earth.
In late August there are more living things here than at any other time of the year. But winter is around the corner and there are just two months for all Yellowstone's animals to get ready or get out. An early dusting of snow is a sign for elk to start
In winter, Yellowstone is frozen solid - locked in snow as deep as a house for over six months. As we follow the grip of winter over the course of six freezing months, we chart the fortunes of Yellowstone's wildlife in a finely balanced fight to survive.
