2016 Map of Hughes D-3 NE

About this map

The Continental Divide traverses the southern reaches of this landscape, marking a significant hydrologic boundary in the remote Alaskan interior. The northern half of this territory is largely defined by the protected wilderness of the Gates Of The Arctic National Preserve, where the terrain rises toward the elevations of the Helpmejack Hills. Winding through the central and southern valleys, the Hogatza River creates a drainage system that separates the high ridges. This 2016 survey also captures the administrative boundary between the Northwest Arctic Borough and the Yukon-Koyukuk Census Area, providing a precise look at how these modern geopolitical lines intersect with the natural topography of the Brooks Range foothills.
