Alaska sometimes experiences two sunsets in one day; Alaska is the only U.S. state with coastlines on three seas; and Alaska is the northernmost, westernmost and easternmost U.S. state. Due to its long summer days, vegetables sometimes grow enormous in Alaska, where a head of cabbage once grew to 94 pounds. At certain times of year, there are places in Alaska that get 24 hours of daylight, while at other times, some places get 24 hours of darkness.
For complex reasons related to a unique combination of latitude, longitude and time zone, parts of northwest Alaska sometimes experience double sunsets. The sun sets just past midnight and then sets again just before midnight the same calendar day, a few minutes less than 24 hours later.
Alaska has coastlines on the Pacific Ocean, the Arctic Ocean and the Bering Sea.
The nothernmost spot in the United States is Point Barrow, Alaska, and the westernmost is Amatignak Island, Alaska, about 50 miles from Pochnoi Point, Alaska. Although Pochnoi Point is about 50 miles west of Amatignak Island, it is the easternmost point in the United States because it falls to the west of the 180 degree longitude line, which divides "east" from "west" by convention.
In 1867, U.S. Secretary of State William Seward purchased Alaska from Russia for about two cents an acre. At the time, people ridiculed his act as "Seward's Folly."
