2014 Map of De Long Mountains A-5 SE

About this map

The Singoalik River flows through the southern reaches of this remote terrain, providing a primary drainage feature in a landscape defined by significant elevation changes. This 2014 survey documents a quiet boundary between the North Slope Borough and the Northwest Arctic Borough, which cuts across the lower third of the map. Aside from these administrative lines and the waterway, the area remains largely devoid of modern development, showing the natural state of the De Long Mountains area. Local topography is recorded through fine contour intervals, tracing the ridges and valleys that separate the river drainage from the high ground to the north, offering a clear view of the land's form without the interference of man-made structures.
