Arctic National Wildlife Refuge
If you think of sprawling coastal plains and seemingly endless streams of caribou, you're probably thinking of the Arctic National Wildlife Refuge (ANWR to locals).
This massive refuge may be best-known for the highly public battle over whether to open its borders to oil drilling, but this vast, trackless wilderness is also home to more than 200,000 caribou and a smattering of polar bears, best seen from the tiny village of Kaktovik.
