1962 Map of Demarcation Point D-3

About this map

Humphrey Point and the coastal lagoons of the Beaufort Sea dominate this mid-century arctic landscape along Alaska's northern coast. The map reveals the intricate shoreline geography where the Angnun River and Sikulahtukvik River meet the tidal waters of Angnun Lagoon and Pokok Lagoon. This 1950s-era survey captures the specialized infrastructure of the far north, showing a Landing strip and Tower at Nuvagapak Point, alongside a Tractor Trail that provides the primary overland route across the tundra. The mapping represents a transition in arctic exploration, utilizing photogrammetric methods from 1958 and coastal hydrography to detail the shifting sands and mudflats of Nuvagapak Lagoon.
