1955 Map of Barrow A-4

About this map

Sungovak Lake and Sukok Lake dominate this 1955 landscape of the Arctic coastal plain within Naval Petroleum Reserve No. 4. The area is defined by its complex hydrography, featuring numerous elongated thermokarst lakes such as Evrulivik Lake and Kimouksik Lake, which reflect the region's permafrost-driven geography. Early industrial exploration is evidenced by Gas Well No 3 (Abandoned) and a sparse network of Tractor Trails that provided the only overland access across the marshy tundra. From the shores of Nunavak Bay to the inland waters of Ikroavik Lake, the map captures a period of government-led resource assessment and mapping in the Alaskan wilderness before more modern infrastructure arrived.
