Demarcation Point, Beaufort Sea

Demarcation Point is at the end of a 2.5 miles long (4 km) spit between Demarcation Bay and the Beaufort Sea. The point was named by Sir John Franklin on July 31, 1826 because it is located at longitude 141 degrees west, the boundary between then British and Russian dominions on the northern coast of America. The area was an important winter rendezvous for natives who call it "Pataktak," meaning "place where ducks fly low". The Alaska-Canada border is about 8 miles (13 km) further east and is marked by the Demarcation Line that represents one of the greatest feats of wilderness surveying in history. From 1904 to 1913, the 1538 miles long (2480 km) boundary line between Alaska and Canada was surveyed and marked by 202 metal obelisks and a 20 feet (6 m) wide clear-cut swath.
