About this map

Cook Inlet dominates this mid-century survey, revealing the critical maritime and industrial geography of the Kenai Peninsula. The map highlights the early development of offshore energy resources, marking numerous installations such as Oil Platform Bruce, Oil Platform Anna, and Oil Platform Granite Point. These industrial landmarks stand in contrast to the natural hazards of the inlet, including the extensive Middle Ground Shoal and the shifting Tidal Flat zones.

Near the shoreline, the survey captures the beginning of inland infrastructure with the North Kenai Road and clustered Cabins along the coast. Topographical features like Boulder Point and Jumbo Rock near Nikishka Bay provide essential landmarks for navigation. Inland, the landscape is dotted with small water bodies such as Suneva Lake, reflecting the low-lying, water-dense terrain characteristic of the region during this era of northern development.
