2015 Map of De Long Mountains A-3 NE

About this map

De Long Mountains terrain dominates this 2015 survey of a high-latitude wilderness where the headwaters of the W Fork Wulik River carve through a landscape defined by sharp elevation shifts and expansive drainage basins. The map illustrates a political boundary of significant geographic scale, tracing the line where the North Slope Borough meets the Northwest Arctic Borough. This area is characterized by its isolation and lack of human infrastructure, focusing entirely on the natural hydrography and topographical contouring that shape the northwestern Alaskan interior. Surveyors from the U.S. Geological Survey documented the intricate flow of the river's western fork as it meanders through the foothills, providing a clear view of the drainage patterns essential for understanding this subarctic environment.
