1964 Map of Demarcation Point

About this map

Demarcation Point stands at the far northeastern edge of the Alaskan wilderness, where the United States Canada international boundary meets the Beaufort Sea. This mid-century survey illustrates a landscape of extreme transitions, moving from the glacial peaks of the Romanzof Mountains and British Mountains down across the coastal plain to a complex network of lagoons and reefs. The settlement of Gordon and the Pingokraluk site represent the sparse human footprint on the Arctic Ocean coast, while the presence of the McCall Glacier and Mt Hubley highlights the high-altitude ice fields of the Brooks Range. Numerous braided waterways, including the Kongakut River and Aichilik River, drain into coastal features like Demarcation Bay and Angun Lagoon, defining the drainage patterns of the North Slope.
