1963 Map of Port Moller A-4

About this map

Wosnesenski Island and a series of smaller landmasses punctuate the vast waters of the Pacific Ocean in this mid-1960s hydrographic and topographic study. Based on aerial photography from 1957 and field annotations from 1963, the map depicts the complex seafloor contours and island coastlines of the Aleutians East region. The archipelago is represented by several distinct points of land, including Omega Island to the north, the small cluster of Kennoys Islands further east, and Clay Island. While primarily a nautical and topographic record produced by the Geological Survey and USC&GS, the map emphasizes the maritime isolation and natural geography of these islands rather than human settlement. The inclusion of depth curves and soundings provides a detailed look at the underwater shelf surrounding these remote outposts during a period of active aerial surveying in Alaska.
