1958 Map of Iliamna D-1

About this map

Chinitna Bay and the surrounding Iniskin Peninsula define this coastal landscape at the western edge of Cook Inlet. The map documents a period of industrial interest in the Alaskan wilderness, evidenced by a Pipeline and an Oil Well located south of the bay near Gaikema Creek. The glacial activity that continues to shape the region is visible in the massive Umbrella Glacier and its subsequent outwash plains, where the Right Fork and West Fork rivers originate. Early human presence is minimal, noted only by an isolated Cabin near the shoreline. Topographic details like Havenstrite Ridge and South Chinitna Mountain rise sharply from the mudflats, providing a clear picture of the area's geological complexity before modern development altered the coastline.
