1955 Map of Umiat D-3

USGS Topo · Published 1971

About this map

The Colville River carves a massive, braided path through this Arctic landscape, where the meandering Kogosukruk River and Kikiakrorak River feed into its expansive basin. The 1955 topography captures the North Slope in a state of primitive natural flux, characterized by a dense network of thaw lakes and ponds scattered across the tundra. Notable landmarks like Sentinel Hill and the prominent Ishukpak Bluff rise above the riverbanks, serving as vital orientation points in an otherwise low-lying wilderness. This region is significantly defined by its administrative status, as it sits within the Naval Petroleum Reserve No 4 Boundary, illustrating the mid-century strategic importance of Alaska's northern mineral and oil resources before the era of modern development.
