1958 Map of Valdez D-3

About this map

The Copper River dominates this interior Alaskan landscape, shown here as a wide, braided waterway winding through the southern half of the quadrangle. In the late 1950s, the Edgerton Highway provided the primary terrestrial corridor through this region, running southwest of the river near Willow Creek. The terrain is defined by the convergence of major glacial runoff, with the Nadina River and Dadina River carving deep valleys through the northern forest and muskeg before joining the main river system. Near the eastern edge, Dadina Lake sits in a high basin under the shadow of VABM 2340 Dadina, a primary geodetic control point used during the photogrammetric mapping of this territory. This survey captures the region's geography just as the Copper River Base Line established the formal surveying grid for future land claims and resource management in the Copper River Valley.
