2021 Map of Trinity Islands C-3 SE

About this map

Tugidak Island, part of the larger Trinity Islands archipelago, occupies the southeastern corner of this maritime-focused survey in the Gulf of Alaska. The landscape is dominated by the vast expanse of the open ocean, which covers nearly the entire map area, with the landmass of the island providing the only topographical relief. Detailed bathymetric or maritime boundaries are indicated by the inclusion of the t42s r35w township designation, anchoring this remote coastal region within the Public Land Survey System. The map illustrates the shoreline of the island where it meets the sea, capturing the isolate and shifting environment of the Kodiak Island Borough at the start of the 2020s.
