About the Show

No place on Earth is like Yellowstone – an extraordinary world of fire and ice atop America’s largest volcano. In summer, it’s a wildlife paradise and a time of plenty for grizzly bears, wolves and hundreds of other animals. In winter, it forces them into a struggle for survival. Not all will make it. Situated above the rocky mountains, this extreme wilderness always tests its wildlife. To succeed, every creature has its own survival strategy.
