2021 Map of Trinity Islands D-1 SW

About this map

Cape Alitak and the finger of land extending toward Tanner Head define this maritime landscape at the southwestern edge of Kodiak Island. This map records a sparsely populated coastal environment where the land yields abruptly to the Gulf of Alaska. The presence of the Alitak Shoal just offshore highlights the navigational hazards inherent to this subarctic coastline. Most of the sheet is occupied by the open sea, underscoring the isolation of these landforms. The terrestrial portion is marked by sharp elevation changes and the specific Public Land Survey System boundaries of t38s r32w and t38s r31w, which provide a formal grid over the wilderness. This survey is a snapshot of an area where maritime and land-based features are the primary landmarks for those navigating the Alaskan coast.
