1963 Map of Sutwik Island C-4

About this map

Sutwik Island dominates this maritime survey, situated in the coastal waters of the Pacific Ocean south of the Alaska Peninsula. Compiled from 1957 aerial photography and 1963 field annotations, the map details the complex topography and shoreline of this uninhabited landmass. Notable coastal landmarks include the prominent Foggy Cape at the island's eastern extremity and the smaller Hydra Island located to the northeast. The interior is defined by steep elevation contours, while the surrounding waters feature hydrographic depth soundings adapted from USC&GS charts, illustrating the nautical environment of the mid-1960s before modern satellite mapping.
