About this map

National Petroleum Reserve in Alaska dominates this 1984 survey, illustrating a massive expanse of the North Slope where the Arctic landscape remains largely defined by its natural water systems. The Awuna River meanders across the northern portion of the quadrangle, while the southern boundary is shaped by the wide course of the Colville River and its tributary, Grayling Creek.

A singular Drill Hole and a remote Tractor Trail are the only indicators of human infrastructure in this region during the early 1980s, highlighting the area's primary role as a petroleum resource zone rather than a site of permanent settlement. The prominent elevation of Lookout Ridge runs east to west through the center of the sheet, providing a stark topographical break between the river basins. This map preserves the mid-century state of Alaska's northern wilderness before modern technological shifts altered the methods of Arctic exploration and land management.
