About this map

Knight Island dominates the eastern reach of this coastal landscape, where the waters of Prince William Sound carve a complex system of deep-water inlets and protected coves. Within the boundaries of the Chugach National Forest, the map reveals a maritime environment shaped by glacial activity and tectonic forces, evidenced by the sheer drop-offs at Mountain Point and the narrow passage of Long Channel. Small archipelagos like the New Year Islands and Clam Islands dot the western waters, providing vital navigational markers for the region's historic coastal trade.

The intricate shoreline is punctuated by secluded harbors such as Snug Harbor and Port Audrey, which have served as essential refuge points for mariners. The terrain rises sharply from the water's edge, with labels like Cat Head and Mallard Head marking prominent coastal elevations. This 2018 survey provides an exacting look at the interplay of land and sea in the Unorganized Borough, capturing the distribution of named islands including Mummy Island, Squire Island, and Aguliak Island.
