A Caribou Journey

A single line of caribou stretches for miles across the frozen tundra of Alaska. Sounds of clicking hooves echo through the air as the herd follows the centuries-old migration route. With their thick coats and their padded, shovel-like hooves, caribou are ideally adapted to the snowbound environment. This in-depth look at the caribou explores their habits and habitat, their interactions with herd members and other arctic wildlife, and the dangers that await the young, the old, and the weak along these ancient trails.
