Yellowstone

In winter, Yellowstone is frozen solid, locked in snow as deep as a house for over six months. Whether you hunt for meat, live off stored body fat or simply hibernate, creatures need to take every advantage to survive. This stunning nature documentary follows foxes, elk, wolves and bison as they attempt to get through this perilous season and conquer Yellowstone's winter wonderland.

As winter turns to spring, temperatures rise and Yellowstone bursts into life.

As winter approaches, animals have only two months to prepare or attempt escape.
