Alaska does not touch other US states. It has borders with Canada, the Arctic Ocean, the Pacific Ocean, the Bering Sea, and the Bering Strait.
The United States bought Alaska from Russia on March 30, 1867. This was called the Alaska Purchase. This prevented Russia from having land on continental North America. Alaska cost $7.2 million. Today, that would be $120 million. The price was about $0.02 per acre ($4.74/km2).
Alaska became an organized (or incorporated) territory on May 11, 1912. It became the 49th state on January 3, 1959.[8]
The name Alaska comes from the Aleut word alaxsaq. This means "the mainland" or "the object towards which the action of the sea is directed."[9] The land is also called Alyeska, which is another Aleut word that means "the great land." The Russian name was Аляска.
Alaska mainly exports seafood, primarily salmon, cod, Pollock and crab. The oil and gas industry is very important in the Alaskan economy. More than 80% of the state's revenues is from petroleum extraction.
