1986 Map of Hughes D-6

About this map

The Kobuk River flows through the southern portion of this landscape, a critical waterway in a region dominated by the Angayucham Mountains. This 1986 provisional edition, based on aerial photography from the early 1970s, documents a vast wilderness where water and elevation dictate the terrain. Much of the northern half is protected within the Gates of the Artic National Preserve, where significant water bodies like Narvak Lake and Selby Lake are situated beneath peaks like Fritts Mountain. The map also identifies Coal Pass, suggesting localized geological interest in an area otherwise defined by its complex drainage network, including the Killak River and the winding course of the Selby River. This survey provides a baseline of the Arctic environment before modern shifts, focusing entirely on the natural hydrology and topographical relief of the Brooks Range foothills.
