1963 Map of Simeonof Island

About this map

The Shumagin Islands are depicted during a period of mid-century maritime surveying, focusing on the isolated geography of the Pacific Ocean south of the Alaska Peninsula. Central to this map is Simeonof Island, largely encompassed by the Simeonof Nat Wildlife Rfg, an area established for the protection of sea otters and diverse avian life. The surrounding waters are charted with bathymetric soundings and depth curves, including the hazardous Twelve Fathom Strait and Otter Strait. To the west, the southern tip of Nagai Island is shown with landmarks such as Sadler Peak and the curiously named Saddlers Mistake. These islands represent a critical intersection of marine conservation and navigation, with smaller outposts like Chernabura Island and Bird Island providing vital data for the Usc&GS hydrographic charts of the 1960s.
