About this map

The Alaska Yukon border defines the eastern edge of this landscape, where the northernmost reaches of the Brooks Range meet the Arctic Ocean. High peaks of the Romanzof Mountains, including Mt Isto and Mt Hubley, overlook a complex system of glaciers and braided rivers that flow toward the Beaufort Sea. The map captures the coastal transition at Demarcation Bay, where the United States Canada international boundary intersects the shoreline near the former settlement of Gordon (Aband).

Inside the Arctic National Wildlife Range, the terrain is marked by traditional points of coastal importance like Humphrey Pt and Nuvagapak Pt. A lone Tractor Trail provides a trace of mid-century transit along the coast, connecting old sites such as Kuluruak (Site) to the Kongakut River delta. The presence of numerous survey markers, including VABM 2419 Mosquito and VABM 6564 Grizzly, indicates the precision of this 1955 field work in a region where the Continental Divide dictates the flow of the Jago River and Aichilik River.
