North America still contains some of the world's greatest untamed lands - from the vast expanse of northern tundra known as the Canadian Shield to the soaring peaks of the Rocky Mountains, and the great Alaskan wilderness in the west.

Whether it's watching the killer whales and spirit bears of the Pacific northwest, visiting the wolves and buffalo of Yellowstone, or seeing grizzlies on Kodiak Island, you'll find a wealth of wildlife amidst a backdrop of some of the planet's most impressive scenery.
