Bear Island

Chichagof Island, Southeast Alaska, is Jurassic Park -- in real time. Its dense rainforests hide more grizzlies per square mile than any other place on Earth. In summer, its surrounding waters erupt with life, as herring congregate and salmon are returning to their rivers of birth. This plenty lures some of the most enigmatic predators on Earth -- humpbacks whales and grizzly bears. The program follows veteran tracker Vern Beier, as he meets Chichagof's brown bears on their own turf -- in the deep, dark forests of Bear Island.
