1949 Map of Iliamna C-1

About this map

Cook Inlet defines the coastal character of this remote Alaskan terrain, where the rugged shoreline of the Kenai Peninsula meets the waters of Oil Bay and Dry Bay. Mapped through reconnaissance topography by the Geological Survey and Corps of Engineers, the landscape is marked by sharp elevations including Shark Tooth and Mt Pomeroy. The lack of established roads or settlements in the late 1940s highlights the isolation of this region, which was instead defined by its maritime landmarks like Oil Point, Chinitna Point, and the hazardous Oil Reef. Inland, the drainage network of Portage Creek and Fitz Creek cuts through the high ground of Front Mtn and Bald Hill, illustrating the complex coastal watershed before modern development.
