Eastern Arctic coast
On the eastern part of the coast of the Arctic Refuge, the Kongakut River empties into a narrow channel of Beaufort Lagoon between the coast and Icy Reef, a 16-mile-long barrier reef. Further east is Demarcation Point and Demarcation Bay, lying nearly on the longitude line at 141 degrees west, the boundary between Alaska and Canada. Orth's Dictionary of Alaska Place Names tells us that Demarcation Point and Icy Reef were named by Sir John Franklin in July and August of 1826. In Franklin's time, Alaska and Canada were owned by Russia and Britain, respectively. Orth reports that the area around Demarcation Point was "an important winter rendevous of the Eskimo."
