1955 Map of De Long Mountains B-3

About this map

The De Long Mountains dominate this remote Alaskan landscape, where the headwaters of several major regional drainage systems originate. Rising from the north, Mount Kelly serves as a prominent landmark overlooking a network of arctic waterways. The Ipewik River and Kukpuk River carve through the northern and central sections of the quadrangle, while the Kivalina River and Sognerak River drain the southern reaches. Published for civil use by the Geological Survey and mapped by the U.S. Army Topographic Command, the survey reflects the mid-century effort to document the Brooks Range foothills using aerial photogrammetry. The absence of roads or trails highlights the undisturbed nature of this wilderness at the time of the 1955 field annotation, where the terrain is defined entirely by its complex contour elevations and seasonal river flow patterns.
