Polar bear… immensely powerful, ferociously cunning, lethally equipped for devastating exploitation of its frozen realm. Legendary for its endurance, hunting prowess and awesome strength, it is the largest and most formidable land predator of the planet’s most brutally unforgiving environment. Venture into the trackless Arctic wastes to witness the uncanny survival strategies developed by this magnificent creature – tactics honed to a killing edge during 250,000 years of adaptation to its icy kingdom. See why the largest of these fearsome bears, weighing more than two full-grown lions, stands as the undisputed predatory monarch of a pristine, unconquered land where man still ventures at his peril.

The powerful McNeil River Falls is a very popular nursery spot for growing grizzly bears. Every summer, hundreds of the huge animals gather at the falls to feast on migrating salmon and find mates.

Completed in 1900 with British financing, Canadian contracting and American engineering, the White Pass & Yukon Route was the engineering marvel of its time. Cutting a swath through some of the world's most ruggedly beautiful terrain, the White Pass today is a trip through history.

This video examines the grizzly bear, one of nature's greatest predators. It is part of a multi-volume Time Warner series that markets the ferocious, killing aspects of various wild animals.
