Pack Life At Yellowstone National Park, White Wolf, Real Wild

In the of Yellowstone National Park lies Hayden Valley, where in the winter months it can reach temperatures of 40 below with up to 20 feet of snow. Few animals can survive in these conditions, and the wolves that currently live there were hunted to extinction and gone for almost 80 years. With their reintroduction to the Park in the late 1990s, this documentary intimately looks at the lives of both the Hayden pack and the Canyon pack.
