1963 Map of Sutwik Island C-4

About this map

Sutwik Island dominates the southern half of this 1963 survey, standing as a prominent landmass within the Pacific Ocean. The map captures the island's topographic character through intricate contour work based on 1957 aerial photography, highlighting the elevations that rise above the surrounding waters. To the northeast, the smaller Hydra Island is visible, while the easternmost reach of the main island is marked by Foggy Cape. Published in the early 1970s, this document integrates hydrographic data from the U.S. Coast and Geodetic Survey to provide a clear picture of the maritime boundary between the land and the sea. The absence of roads or developed settlements on the island emphasizes its isolated nature during the mid-20th century, serving as a specialized record of the Alaska Peninsula's coastal islands.
