ALASKAN GRIZZLIES

In a flash of liquid silver, a salmon leaps from a foaming cascade. An Alaskan brown bear captures it in its jaws in midair.

The largest grizzlies in the world, perch on its banks to gorge on the river’s bounty during this annual summer feast. And where the river tumbles into the sea, bears are here, too, foraging for clams and loping along the beach.

Here in Katmai National Park in the heart of the Alaskan wilderness, we have a rare encounter with Ursus arctos in all its wild majesty.
