Alaska's Grizzly Gauntlet

Survivalist Les Stroud takes a look at the amazing survival skills used everyday by the black bears in the Alaskan wild. Plus, how the bears ambush the salmon as they swim up the rivers to spawn.

Deep in the Alaskan interior, Les Stroud tracks the survival skills of the moose for the upcoming mating season.

Les suffers the difficult task of trying to keep up with herds of migrating caribou. The Alaskan species of reindeer travel south during winter months, at a speed of up to 80 kilometres an hour.

Les Stroud travels to the edge of the Alaskan Arctic to find out how polar bears are being forced to adapt to their rapidly changing environment.

A survivalist makes his way to Karluk Lake on Kodiak Island so that he can embed himself with the biggest brown bears as the animals prepare for a long hibernation.
