About this map

Knight Island dominates this maritime landscape, its deeply indented coastline forming a complex network of sheltered anchorages within Prince William Sound. The terrain is characterized by steep, glacially-sculpted ridges that fall directly into the sea, protected under the administration of the Chugach National Forest. Numerous small inlets such as Mummy Bay, Lucky Bay, and Hogan Bay illustrate the coastal morphology of the region, where narrow channels like Long Channel and Knight Island Passage separate the main landmass from smaller outcrops like Squire Island. The absence of developed roads or settlements emphasizes the wilderness character of the area, where land use is defined by natural features like Sandra Lake and the navigational significance of points such as Point Helen at the southern tip of the island's eastern arm.
