2024 Map of Blying Sound D-4 NE

About this map

Evans Island and Elrington Island dominate this coastal survey of the Prince William Sound region, where steep island topography meets the open Gulf of Alaska. The settlement of Chenega is situated on the northeastern tip of Evans Island, overlooking the waters of Squirrel Bay. This area of the Chugach National Forest is defined by a complex maritime geography of sheltered inlets and exposed capes, including the deep indentations of North Twin Bay and South Twin Bay. The map traces the natural corridor of Elrington Passage, a vital waterway separating the major landmasses. The southern reaches of the map terminate at Point Elrington, where the land drops away into the open gulf. This modern survey provides an exact record of the shoreline and elevation contours for these remote islands, from the tidal flats of Koss Cove to the high ridges above Fox Farm Bay.
