2021 Map of Afognak B-0 SW

About this map

Afognak Island defines the western portion of this maritime survey, showing the rugged coastline and interior elevation contours of this northern Kodiak archipelago landscape. The map is dominated by the open waters of the Gulf of Alaska and Marmot Strait, reflecting the area's isolation and reliance on sea-based navigation. Because there are no roads or settlements printed on this portion of the island, the data highlights the raw physical geography, documenting the precise shoreline and tidal zones as they existed in the early twenty-first century. This level of detail is critical for understanding the coastal morphology and maritime boundaries of the region, including the township and range lines such as t22s r17w and t21s r16w that segment the wilderness and surrounding waters into the Public Land Survey System grid.
