2015 Map of De Long Mountains A-4 NW

About this map

The North Slope Borough and Northwest Arctic Borough boundary line divides this Arctic landscape, marking a jurisdictional threshold in one of Alaska's most northern reaches. This 2015 survey by the U.S. Geological Survey illustrates the transition between these two massive administrative districts. The terrain is defined by its drainage systems, most notably the Kukpuk River flowing through the northern sections and the Kivalina River winding through the southern portion of the quadrangle. These waterways are central to the geography of the region, dictating the flow of the land across the various township and range divisions, including t33n r25w and t32n r24w.
