1955 Map of Demarcation Point C-3

About this map

The Arctic National Wildlife Range defines the vast landscape of this 1955 survey, capturing a remote section of the North Slope where the land meets the Beaufort Sea. The terrain is dominated by a complex braided water system, with the Aichilik River and Kogotpak River cutting across the northern reaches toward the coast. Further south, the map reveals the transition from coastal plains to the rising elevations of the interior, where the Egaksrak River and Ekaluakat River carve their paths through the mountains. Mapped by the Army Map Service using aerial photography, the sheet reflects an era of intensive northern surveying where land lines were predetermined by the Bureau of Land Management but remained largely unsurveyed on the ground. The lack of named human settlements emphasizes the character of the region as a preserved wilderness at the time of the map's creation.
