1951 Map of Demarcation Point

About this map

The Alaska Yukon border meets the Arctic Ocean at the far northeast corner of this territory, where the United States Canada boundary line runs straight through the British Mountains. The landscape is dominated by the massive peaks of the Brooks Range and the Romanzof Mountains, with high-elevation survey markers like Vabm 6566 and Vabm 5620 indicating the height of the terrain. The northern coastline is a complex network of barrier islands and lagoons, including Siku Lagoon and Beaufort Lagoon, protected by features like Icy Reef. Small settlements such as Gordon and Demarcation sit on the shores of Demarcation Bay, while the site at Kuluruak points to shifting habitation patterns along the coast. This 1951 survey integrates older 1911 International Boundary Commission data with mid-century aerial photography to map the drainage of the Jago River and Kongakut River.
