2015 Map of De Long Mountains B-1 SE

About this map

Noatak National Preserve encompasses the majority of this landscape, where the high-latitude terrain is defined by the drainage of the Kelly River. The survey illustrates the stark, unpopulated character of the Arctic wilderness within the De Long Mountains during the mid-2010s. A significant administrative line bisects the area, marking the boundary between the North Slope Borough and the Northwest Arctic Borough. This boundary transition represents the jurisdictional shift between two of Alaska's largest and most remote municipal divisions. The map provides a detailed view of the natural relief and hydrologic patterns in a region where topography dictates the flow of water and travel, entirely devoid of roads or permanent settlements.
