About this map

Chenega Island dominates this portion of the Chugach National Forest, its convoluted coastline defining the western margins of the Prince William Sound. The terrain is characterized by steep coastal slopes and sheltered inlets, including Chenega Cove and Kake Cove at the island's southern end. These natural harbors, alongside Masked Bay to the north, illustrate the intricate maritime geography that has historically shaped navigation and subsistence in this Alaskan wilderness.

The waters of Dangerous Passage separate the island from the mainland to the west, while the eastern shore faces the Knight Island Passage. This 2018 survey documents the precise coastal features such as Ewan Point and Chenega Point, which serve as critical landmarks for marine traffic. The absence of roads or permanent settlements emphasizes the character of the region as a preserved landscape within the national forest system.
