Nature's dramas play out in one of the most remarkable ecosystems on Earth: Yellowstone.

It's a place where snow meets fiery underground forces, where waters travel from Rocky Mountain peaks to the Great Plains, and where age-old battles between predator and prey take place. This is Yellowstone, home to some of the most spectacular landscapes and wildlife in America. Join host Bill Pullman on an exploration of its colorful springs and raging waters, its glittering winters and lush summers, and its returning packs of predators and vast array of winged creatures.
