About this map

Nagai Island occupies the southern portion of this mid-century maritime survey, situated where the West Nagai Strait and East Nagai Strait converge. The northern tip of this island is marked by Cape Wedge, a prominent landform that guides vessels transitioning from the open waters of the Pacific Ocean into the straits. A solitary Light is located at this northern extremity, serving as a critical navigational aid for the maritime traffic of the era.

The landscape is characterized by its isolation and lack of human infrastructure beyond maritime safety markers. Topographical data on Nagai Island reveals a complex interior of elevations, while the surrounding hydrography reflects the depth and character of the coastal waters as they were mapped in the early 1960s. This survey records the shoreline and bathymetry prior to modern coastal changes, documenting a remote section of the Aleutian chain through photogrammetric methods and hydrographic data compiled from coastal charts.
