1951 Map of Icy Bay D-2 and D-3

About this map

The Robinson Mountains define the northern limit of this coastal landscape, where the southern slopes meet the shifting waters of the Gulf of Alaska. Surveyed just after the war, the map reveals a remote maritime environment dominated by glacial drainage and intricate shoreline features like Claybluff Point and Icy Cape. The eastern portion of the sheet is centered on the complex of Riou Bay, protected by the treacherous Moraine Reef and the isolated Moraine Island. Small isolated Cabin symbols near Mud Bay and Carson Cr indicate the rare human footprints in this wilderness, likely used by hunters, fishers, or early coastal surveyors. These structures, along with the North Base and South Base landmarks, provide specific points of interest for historical researchers and cartographic enthusiasts studying the evolution of the Alaskan coastline before modern development.
