About this map

The Copper River delta dominates this coastal landscape, showing an intricate network of glacial runoff and tidal influence as it met the Gulf of Alaska in the early 1950s. The terrain is defined by a labyrinth of waterways, including Glacier Slough, Alaganik Slough, and Pete Dahl Slough, which weave through silty tidal flats and large landforms like Castle Island. Near the settlement of Alaganik, the presence of a Cem and Pipeline Lake suggests the footprint of earlier infrastructure along the coastal corridor.

Upland areas to the northeast provide a sharp contrast, rising toward McKinley Peak and Mc Kinley Lake, where a Mine is located near the headwaters of Salmon Creek. Closer to the coast, the Cordova Airport and its associated Radio West Tower represent mid-century aviation developments, while the shifting nature of the coastline is visible in the offshore bars like Grass Island Bar and Kokinhenik Bar.
