Alaska's state flag features The Big Dipper ("Ursa Major" or "Great Bear" constellation) as a symbol of strength, and Polaris (the North Star ) as a symbol of Alaska's northern location and "the ever constant star for the mariner, the explorer, hunter, trapper, prospector, woodsman, and the surveyor..." (quote from legislation). The blue background represents the sky, sea, lakes, and wildflowers of Alaska (the official state flower is also blue). All State Flags
History of Alaska's Flag
The Alaska state flag (selected for its simplicity, originality, and symbolism) was created by Benny Benson, a 13-year-old 7th grader from an orphanage in Seward, Alaska (John Bell Bensona; 1913-1972). Seward honors him with a monument on 3rd Avenue. Alaska's state song is titled "Alaska's Flag."
Notes: The North star is also found on the state flag of Maine. The Big Dipper constellation also contains "The Delaware Diamond" (state star of Delaware).
