1984 Map of Lookout Ridge D-4

About this map

National Petroleum Reserve in Alaska dominates this 1980s landscape, representing a vast Arctic expanse defined by complex water systems and survey markers. The Avalik River meanders across the territory, illustrating the intricate drainage patterns of the North Slope. Named topographic points such as Kieth, Omega, Omicron, and Sigma serve as critical reference landmarks in an environment largely devoid of permanent settlements or infrastructure. Based on aerial photography from 1971, the map provides a precise record of the shoreline and swamp distributions before later environmental shifts, offering a baseline for researchers studying Arctic hydrology and land management boundaries within the reserve.
