1984 Map of Utukok River D-1

About this map

The Ketik River meanders across this northern landscape within the National Petroleum Reserve in Alaska, defining the drainage patterns of this Arctic territory. This 1984 survey, based on photogrammetric methods from 1971, documents a vast expanse of thaw lakes and wetlands typical of the North Slope. The topographical data, captured during a period of significant federal land management and resource evaluation, provides a precise record of the shoreline and elevation contours of the basin before later shifts in the permafrost environment. The map serves as a vital baseline for understanding the physical geography of this remote region, where water bodies and subtle elevation changes are the primary landmarks across the tundra.
