Wild Giants of Denali (1970)

Sinopsis

Denali comprises six million acres of pristine Alaskan wilderness, one of the largest protected natural habitats on Earth. It is home to some of the continent's most dramatic and powerful animals: grizzly bears, wolves, moose. This great National Park is a remnant of times long past when Nature ruled. Now, a human-animal partnership has evolved to safeguard the park and its mammoth inhabitants.
