1985 Map of Ikpikpuk River B-5

About this map

The National Petroleum Reserve in Alaska dominates this landscape, reflecting a mid-1980s period of federal land management and resource evaluation in the North Slope Borough. This specific area is defined by its drainage systems, most notably the meandering course of the Kigalik River which winds across the southern half of the sheet, and the Titaluk River in the northwest corner. The terrain is structured by the Base Line, a critical surveying marker for the Township and Range system in this expansive environment. Without roads or permanent settlements, the map provides an exacting record of the natural hydrology and topographical relief as it stood prior to modern industrial shifts in the Arctic interior.
