1952 Map of Cordova B-3

About this map

The Martin River Delta dominates this coastal landscape, where the glacial silt of the Copper River meets the Gulf of Alaska. Photogrammetric methods from 1950 capture a complex network of shifting waterways, including Long Island Channel, Hotcake Channel, and the Kokinhenik Branch. These channels weave between massive tidal deposits of mud and sand, illustrating the dynamic nature of the deltaic environment in the early 1950s.
