2015 Map of De Long Mountains A-3 SE

About this map

The high Arctic peaks of the De Long Mountains dominate this remote portion of the Northwest Arctic Borough. The Wulik River and the W Fork Wulik River wind through the township boundaries of t31n r20w and t31n r21w, shaping the hydrology of this treeless tundra landscape. Distinctive peaks like Ilatsutigrak Mtn and Punupkahkroak Mtn provide the primary navigational landmarks in a region largely defined by its lack of permanent settlements or infrastructure. The presence of Ferric Cr in the northeastern quadrant suggests the mineral-rich nature of the local geology, characteristic of the northern Brooks Range foothills. This 2015 data from the U.S. Geological Survey illustrates the intersection of modern satellite imagery and traditional topographic mapping in one of the most secluded environments in Alaska.
