1951 Map of Iliamna A-3

About this map

Kamishak Bay dominates this coastal survey, where the Alaska Peninsula meets the Cook Inlet waters. The shoreline is defined by extensive Tidal Flats and protected inlets like Akumwarvik Bay. To the east, the Douglas River cuts through the steep, unnamed coastal peaks that rise sharply from the water's edge. This 1951 study, updated in the late 1960s, documents a wild and uninhabited stretch of the Kenai Peninsula Borough before modern development, noting offshore features like Nordyke Island and the prominent Chenik Head. The map's detail on bathymetry and topography provides a clear look at the geological forces shaping this subarctic coast, where heavy siltation and glacial runoff influence the shifting Tidal Flat formations near the river mouths.
