Arctic National Wildlife Refuge turns 50

The Arctic National Wildlife Refuge is one of the most remarkable and remarkably diverse US national wildlife refuges–the Serengeti of North America with its annual caribou migration. Also it a political bone of contention because of the oil wealth under the permafrost and off its shores.

Fifty years ago today, legislation creating the refuge was signed by Secretary of the Interior Fred Seaton.
