1955 Map of Utukok River A-5

About this map

Archimedes Ridge dominates the central topography of this Arctic landscape, where the Kokolik River winds through the western reaches. The map highlights a remote portion of the Naval Petroleum Reserve No 4 Boundary (Indefinite), reflecting mid-century strategic land management in the Far North. Small lakes such as David, Kelly, and Beno are scattered across the tundra, providing some of the few named landmarks in a region largely devoid of permanent settlements or infrastructure. Surveyed by the Army Map Service using aerial photography from the mid-1950s, the terrain is characterized by intricate contour intervals that reveal the complex drainage patterns and elevation changes across the North Slope before later modern developments reached this interior wilderness.
