The Living Edens - Season 1 Episode 1 Denali: Alaska's Great Wilderness

Track a year in the life of Alaska's Mount McKinley. Called by Indians "Denali," or "high one," it is the highest mountain in North America. Filmmaker Bruce Reitherman captures all the seasons in this preserved wilderness - from winter darkness, with its temperatures of 60 degress below zero, to the coming of spring with its burgeoning life, to summer with its 20 hours of daylight, and to autumn as the chill returns to the air in mid-September. This land of extreme contrasts is populated by prowling wolves, foraging caribou, hearty Dall sheep, incredible wood frogs and powerful grizzlies, among many others.
