2021 Map of Trinity Islands B-2 NE

About this map

The Gulf of Alaska dominates this maritime survey in the Kodiak Island Borough, capturing a vast expanse of open water and the remote seafloor southeast of the Trinity Islands. Most of the map area is submerged, with only a singular named topographical feature, Dry Rock, located in the northern portion of the sheet. This specific location at the edge of the continental shelf illustrates the navigational hazards of these North Pacific waters. Modern Public Land Survey System divisions, such as t42s r33w and t42s r32w, extend into the gulf, providing a grid-based reference for maritime boundaries and resource management in this isolated maritime environment.
