The state of Alaska covers approximately 570,640.95 square miles of land, according to the U.S. Census Bureau. Known as 'The Last Frontier,' Alaska is the largest of the 50 states, and more than twice the size of the second biggest state, which is Texas.
With a 2013 estimated population of 735,142, Alaska is the least densely-populated state, averaging just 1.2 persons per square mile. Alaska boasts more than three million lakes within its borders, and it is home to Mount McKinley, the tallest mountain peak in the United States, at 20,320 feet above sea level.
The state is neighbored by the Canadian provinces of Yukon Territory to the east and British Columbia to the southeast. Bordering bodies of water include the Beaufort Sea, Arctic Ocean, Bering Sea, Gulf of Alaska and Pacific Ocean.
