Travels to the Edge with Art Wolfe

Arctic National Wildlife Refuge, Alaska (1x6)

:

America's Serengeti? Wilderness or wasteland? Art rafts down the icy Kongakut River to document America's last pure and untamed wilderness. He chronicles the desolate, yet abundant beauty of the tundra and the rugged landscapes of the Brooks Range. He turns his lens on the delicate birds and animals for which the Refuge is a vital habitat and intersects the great Porcupine caribou herd on its annual migration to the coastal plain.
