1963 Map of Sutwik Island A-3

About this map

The Semidi Islands emerge from the Pacific Ocean in this 1960s study of the remote Alaska coastline. The archipelago is dominated by two primary landmasses, Aghiyuk Island to the north and Chowiet Island to the south, both characterized by steep topographic contours and coastal cliffs reaching toward the sea. As the entire land area is contained within the Semidi National Wildlife Refuge, the map lacks human infrastructure, focusing instead on the natural geography and maritime landmarks of the group. Smaller islets like Anowik Island, Kiliktagik Island, and Suklik Island are mapped with precision, showing the intricate shoreline and scattered rocks that define this isolated maritime environment. The survey incorporates hydrographic data from 1967, providing depth soundings and submerged hazards for the surrounding waters.
