Footnotes

^ A: The State of Alaska uniquely crosses or spans the 180 degree East-West Meridian, and The State of Alaska's territory includes many islands and in several areas "water". This uniquely results in (2) two or (3) three different definitions of East-, South- and West-ernmost points.
^ 48: Also the extreme point in the 48 contiguous states
^ 50: Also the extreme point in all 50 states
