Journey with Kirk Johnson to Yellowstone, where wolves, grizzlies, beavers and Great Gray owls survive one of the greatest seasonal changes on the planet. As the temperature swings 140 degrees, cameras capture how the animals cope.

In episode one, learn whether the brutal winter weather will favor predator or prey. Can the grizzlies that emerge early survive? Why are wolves and Great Gray owls in danger of starvation? Find out how Yellowstone’s unique geology affects the mighty bison. 

The series will air every Wednesday from June 21-July 7 at 9pm.
