2015 Map of De Long Mountains A-2 NW

About this map

De Long Mountains terrain dominates this 2015 survey, where the administrative boundary between the North Slope Borough and the Northwest Arctic Borough cuts across the northern reaches. The landscape is defined by the drainage patterns of the Wulik River, which snakes through the central valley, and Ikalukrok Cr in the east. This map provides a technical view of the remote Brooks Range foothills before further 21st-century environmental shifts, recorded with high-precision contour intervals. The absence of permanent settlements or roads highlights the isolation of this Arctic region, focusing instead on the hydrography and elevation data critical for navigating this portion of Northwest Alaska.
