Alaska is a non-contiguous U.S. state on the northwest extremity of North America. It borders the Canadian province of British Columbia and the Yukon territory to the east; it shares a western maritime border in the Bering Strait with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north and the Pacific Ocean lies to the south. Technically a semi-exclave of the U.S., it is the largest exclave in the world.
