2023 Map of Seward B-3 SE

About this map

Knight Island dominates this portion of Prince William Sound, revealing a complex shoreline defined by deep inlets and narrow channels within the Chugach National Forest. The map documents the intricate geography of the southern island reaches, where significant maritime landmarks like Port Audrey and Snug Harbor provide sheltered points along the eastern coast. The terrain is marked by prominent elevations such as Mountain Point and Cat Head, overlooking a series of smaller landmasses including the New Year Islands, Clam Islands, and Mummy Island. This 2023 survey illustrates the modern contours of the sound's interior waterways, from the broad reaches of Drier Bay and Johnson Bay to the smaller recesses of Mallard Bay and Copper Bay. The naming conventions throughout the quadrangle reflect a long history of maritime navigation and local identification in this corner of the Alaska coast.
