Northernmost Points In The US
1. Point Barrow, Alaska
Point Barrow (Nuvuk) is the northernmost point of all the territories in the US. Located at 71掳23'20"N 156掳28'45"W, Point Barrow is a promontory that is situated on the coast of the Arctic Ocean in the State of Alaska. This significant geographical landmark demarcates the limit between the two important marginal seas of the Arctic Ocean, the Beaufort Sea in the east and the Chukchi Sea in the west. Point Barrow was first explored by Frederick W. Beechey in 1826, who named it in the honor of the British geographer Sir John Barrow.
Point Barrow is usually covered with ice throughout the year and only remains ice-free for about two to three months. For several years, the Point has served as a jumping-off point for Arctic expeditions. Archaeological findings have revealed that before the arrival of Europeans to North America, the Point Barrow area was inhabited by the ancestors of the I帽upiat people. The point is also a notable archaeological site and several artifacts of the Thule culture have been discovered from the area.
