2015 Map of De Long Mountains A-4 SE

USGS Topo · Published 2015

About this map

Sapumegrak Mtn dominates the northern horizon of this Arctic landscape, where high-elevation terrain gives way to a network of hydrologic features and valleys. The elevation contours reveal a descent from these peaks toward the Nadviktak Lakes in the south, suggesting a drainage pattern typical of the Brooks Range foothills. In the southwest, the Aupilatuk Hills rise as a secondary upland formation, creating a diverse topographical profile across the region. This 2015 survey by the U.S. Geological Survey utilizes satellite imagery and national hydrography data to delineate the precise boundaries and natural flow of this remote territory, providing an essential record of the surface features before potential environmental or climatic shifts alter the permafrost-influenced terrain.
