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.
