Geography of Alaska
Alaska is one of two U.S. states not bordered by another state; Hawaii the other. Alaska has more ocean coastline than all of the other U.S. states combined. About 500 miles (800 km) of Canadian territory separate Alaska from Washington State. Alaska is thus an exclave of the United States that is part of the continental U.S. but is not part of the contiguous U.S. Alaska is also the only state, other than Hawaii, whose capital city is accessible only via ship or air, because no roads connect Juneau to the rest of the continent.
The state is bordered by Yukon and British Columbia, Canada to the east, the Gulf of Alaska and the Pacific Ocean to the south, the Bering Sea, Bering Strait, and Chukchi Sea to the west, and the Beaufort Sea and the Arctic Ocean to the north.
Because it extends into the Eastern Hemisphere, it is technically both the westernmost and easternmost state in the United States, as well as also being the northernmost.
Alaska is the largest state in the United States in terms of land area at 570,380 square miles (1,477,300 km2), over twice (roughly 2.47 times) as large as Texas, the next largest state, and is the seventh largest country subdivision in the world. If the state's westernmost point were superimposed on San Francisco, California, its easternmost point would be in Jacksonville, Florida. It is larger than all but 16 sovereign nations. Alaska is home to 3.5 million lakes of 20 acres (8.1 ha) or larger.Marshlands and wetland permafrost cover 188,320 square miles (487,700 km2) (mostly in northern, western and southwest flatlands). Frozen water, in the form of glacier ice, covers some 16,000 square miles (41,000 km2) of land and 1,200 square miles (3,100 km2) of tidal zone. The Bering Glacier complex near the southeastern border with Yukon, Canada, covers 2,250 square miles (5,800 km2) alone.
