America the Wild: Yellowstone Winter
Casey Anderson says good-bye to Brutus and treks deep into Yellowstone's backcountry to experience the park like most visitors never will. Casey braves severe cold, snowstorms and dangerous animal encounters as he explores how the park's diverse wildlife prepares for a long, harsh winter. On his more than 40-mile journey, Casey tracks the notoriously elusive mountain lion and follows wild grizzlies as they hunt for food to carry them through hibernation.
