About this map

Knight Island dominates this coastal survey, where its complex shoreline is punctuated by deep inlets and protected anchorages. The interior of the island rises to distinctive peaks such as Horn Mtn, while small freshwater bodies like Sandra Lake sit perched above the saltwater arms. This rugged maritime landscape is part of the Chugach National Forest, reflecting the managed wilderness character of the region.

Waterways define the movement and settlement patterns here, with Knight Island Passage separating the mainland from the islands. To the south, the settlement of Chenega is located near Evans Point, where the land meets the Gulf of Alaska. The map captures the intricate geography of Prince William Sound, detailing numerous named bays including Mummy Bay, Thumb Bay, and Hogan Bay, which have historically served as vital points of access for maritime travel and coastal navigation.
