2021 Map of Trinity Islands B-3 NE

USGS Topo · Published 2021

About this map

Tugidak Island occupies the center of this maritime survey, forming part of the larger Trinity Islands group south of the Kodiak archipelago. The terrain is characterized by a dense network of wetlands and small water bodies that dominate the island's low-lying interior. Bordered by the Gulf of Alaska, the coastline is a complex boundary of shifting sands and tidal flats. The 2021 survey data provides a high-resolution view of this isolated landscape, where the Public Land Survey System grids—including t43s r35w and t42s r35w—impose a geometric order over the irregular, water-soaked geography of the island.
