1951 Map of Cordova C-3

About this map

Copper River flows into its expansive braided delta at the foot of the southern Chugach Mountains, dominating the eastern portion of this mid-century topographic record. The landscape is defined by massive glacial systems, including the Scott Glacier, Sheridan Glacier, and Childs Glacier, all marked with detailed indications of crevasses that reveal the active movement of these ice fields. Peaks such as Mt Williams and Mt O'Neel rise sharply from the ice, serving as anchors for the Chugach National Forest Boundary that spans the terrain. This survey provides a specific look at the drainage patterns and shoreline morphology of the Copper River Delta as it existed in 1951, showing the intricate network of channels around Long Island before more modern geological shifts.
