Alaska is the final frontier of the U.S.

Sparsely populated, disconnected from the contiguous states, subjected to a harsh Arctic climate, and almost unimaginably vast, the mere mention of Alaska conjures images of forbidding wilderness. But it's in these conditions that the U.S. Coast Guard in Alaska must operate.

Dedicated to patrolling Alaska's territorial waters, coming to the aid of damaged vessels, breaking through the routinely sea ice blocked ports, and carrying out scientific studies, the Coast Guard has its work cut out.
