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.
