2021 Map of Trinity Islands C-2 SE

About this map

Sitkinak Island and the neighboring coastline define this maritime landscape in the Kodiak Island Borough. This 2021 study documents the shifting sands and intricate wetland networks that characterize the region, showing the delicate separation between land and the open Gulf of Alaska. The narrow waterway of Tugidak Passage serves as a critical geographic divider between these remote landmasses. While the map is dominated by coastal terrain and hydrographic features, it reflects the modern legal and administrative grid through township and range boundaries such as t42s r32w and t41s r33w. The absence of developed roads or settlements highlights the isolation and ecological character of the Trinity Islands group during the early 21st century.
