Alaska

Alaska is a U.S. state on the northwest extremity of the country's West Coast, just across the Bering Strait. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and territory of Yukon to the east and southeast and has a maritime border with Russia's Chukotka Autonomous Okrug to the west. To the north are the Chukchi and Beaufort seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states Texas, California, and Montana combined, and the seventh-largest subnational division in the world.
