1983 Map of Demarcation Point A-4

About this map

The Romanzof Mountains dominate the southern portion of this 1983 survey, marking a high-altitude landscape where the Continental Divide cuts through the North Slope. This map captures the transition between the high peaks of the Brooks Range and the coastal plain to the north, documenting a region entirely contained within the Arctic National Wildlife Refuge. The braided channels of the Aichilik River serve as a primary drainage for the meltwater of the southern peaks, flowing north toward the Beaufort Sea.
