About this map

Nakalilok Bay and Chiginagak Bay indent the coastline of the Alaska Peninsula in this mid-century survey, revealing a landscape defined by its maritime exposure and coastal topography. The coastline is marked by distinct landforms such as Cape Kuyuyukak and the steep elevation of Cliff. Offshore, the survey documents numerous islands and navigational hazards, including the isolated Central Island and the larger Ugaiushak Island, which features Cabins and a landmark named Hawk.

Evidence of early surveying efforts remains visible through markers like Nakoliok E Base and Nakol. The presence of a Tidal Flat at the head of Nakalilok Bay and features such as Cascade and Logan Reef emphasize the varied coastal environment. This map synthesizes data from the Army Map Service and the U.S. Coast and Geodetic Survey, providing a detailed record of the peninsula before more modern developments altered the mapping of these remote Alutiiq regions.
