Extreme Alaska: Denali

Denali National Park in Alaska is home to the tallest mountain in North America and over two million acres of wilderness. Altitude defines which wild conditions - and creatures - dominate. Join National Geographic as we trek between low and high to experience big game deep in the taiga forest, beautiful subarctic vistas of the tundra, and the challenge of ascending to the top of North America. This National Geographic documentary takes viewers on a scenic tour through Alaska's Denali National Park. Comprising over two million acres of wilderness, the park's impressive landscapes are abundant with a diversity of flora and fauna. This should be of no surprise for a place that's home to glaciers, grizzlies, and North America's tallest peak, Mount McKinley. (official distributor synopsis)
