2021 Map of Trinity Islands C-1 SW

USGS Topo · Published 2021

About this map

Trinity Islands emerge from the Gulf of Alaska in this remote maritime landscape south of Kodiak. The island terrain is defined by dramatic coastal elevations, most notably the high point at Sitkinak Dome and the northern protrusion of Delina Point. These landforms reflect the geomorphology of the archipelago, where steep contours rise directly from the sea. While human settlements are absent from this particular sheet, the mapping of township boundaries like t41s r32w and t42s r31w illustrates the systematic partitioning of the Alaskan wilderness for administrative and public land records.
