1948 Map of Icy Bay D-2 and D-3

About this map

The coastal frontier of the Gulf of Alaska meets the steep ascent of the Robinson Mountains in this 1948 topographic study. Along the shoreline, several isolated Cabin locations serve as the only evidence of human habitation amidst a landscape dominated by shifting glacial runoff. The intricate delta systems of the Lydick River, Big River, and Priest River flow into the shallow waters of Mud Bay, while the prominent hook of Icy Cape marks the entrance to the larger marine reach. This survey documents the complex maritime environment of Riou Bay and the hazardous Moraine Reef, providing a clear record of the shoreline's position before decades of post-war environmental changes. Coastal landmarks such as Claybluff Point and the survey markers at North Base and South Base anchor the topography of this remote stretch of the Alaska panhandle.
