2015 Map of De Long Mountains A-3 NW

About this map

The high-latitude terrain of the De Long Mountains dominates this portion of the Arctic, where the drainage systems and ridgelines serve as the natural foundation for modern administrative boundaries. This map documents the remote intersection where the North Slope Borough meets the Northwest Arctic Borough, a line that follows the height of land across this uninhabited stretch of the Brooks Range. The topographic detail highlights prominent elevation features such as the Wulik Peaks and the carved descent of Kunruk Canyon. As a 2015 study by the U.S. Geological Survey, the map provides an essential record of the physical geography of the western Arctic, capturing the land exactly as it remained before any further industrial or infrastructure development in these northern latitudes.
