2015 Map of De Long Mountains B-1 SW

About this map

Noatak National Preserve encompasses much of this remote Arctic landscape, where the boundary between the North Slope Borough and Northwest Arctic Borough divides the high tundra. The terrain is defined by dramatic elevation changes, notably at Amphitheatre Mtn in the northwest, which rises sharply above the surrounding drainage basins. This 2015 survey details a wilderness devoid of modern infrastructure, focusing instead on the natural hydrology and topographical relief of the Brooks Range foothills. Watercourses like Wrench Cr carve through the northern sections of the quadrangle, illustrating the complex drainage patterns that characterize this protected region of Alaska. The map serves as a primary record of the physical geography and administrative jurisdictional lines in one of the most secluded parts of the American north.
