The call of the wild in Alaska

Most visitors to Denali National Park and Preserve in Alaska come with a checklist for the 'big five' mammals that live here: Grizzly bears, moose, wolves, Dall sheep, and caribou like this small group walking along a ridge. These are barren-ground caribou, a migratory subspecies of caribou found across the arctic band of North America to western Greenland. Barren-ground caribou migrate in large herds, some travelling over 900 kilometres one way, between their summer and winter ranges. But the Denali herd, today which numbers around 3,000 animals, generally stay on the park's 2.4 million hectares. For good reason, too—they're the only large herd that aren't hunted.
