1951 Map of Iliamna A-1 and A-2

About this map

Katmai National Monument defines the southern portion of this coastal survey, where a prominent Monument Boundary separates the protected interior from the waters of Kamishak Bay. The landscape is dominated by the dynamic interaction of water and silt, evidenced by the broad Tidal Flat regions near the mouth of the Douglas River. This era of mapping shows the coastal environment before major modern shifts, capturing specific offshore hazards like Augustine Rocks and the isolated position of Shaw Island in the western Cook Inlet. The absence of roads or trails on the mainland emphasizes the maritime nature of this wilderness at mid-century, where transport and survey work were dictated by the tides and the river system.
