2020 Map of Sutwik Island A-3 OE S NE
USGS Topo · Published 2020About this map
South Island stands as a lonely landform in this remote maritime survey of the Gulf of Alaska. This map documents a small, isolated portion of the Shelikof Strait region, dominated by open water and the rugged coastal outlines of the island chain. The survey reflects the contemporary mapping of the t48s r48w and t48s r47w township and range boundaries across the northern section of the sheet. With minimal terrestrial features, the map emphasizes the maritime expanse and the precise nautical and topographic coordinates required for navigation in these subarctic waters.
