Extreme Alaska: Denali

THURSDAY, JANUARY 10  9P et/pt

Just 200 miles (320 kilometers) from the Arctic Circle, Alaska's Denali National Park is home to the tallest mountain in North America and covers an incredible 6 million acres (2.4 million hectares) of wilderness.  Grizzlies, wolves, and moose roam this terrain, but it is its altitude that defines which wild conditions—and creatures—dominate.  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. Every elevation plays by its own set of rules.
