About this map

Knight Island dominates the maritime landscape of Prince William Sound in this mid-century survey, its deeply indented shoreline forming complex waterways like the Bay of Isles and Snug Harbor. Evidence of mineral exploration appears in the interior, with several mines and a specific Mine located south of Marsha Bay. These industrial markers contrast with the sparse settlement patterns, where only scattered Cabins are noted along the northern shore of Green Island.

Navigational hazards and features are meticulously documented across Montague Strait, from the solitary Pennsylvania Rock to the clustered Manning Rocks. The terrain is characterized by steep peaks like Iron Mountain and coastal features such as the Yellow Cliffs, while maritime activity centers on sheltered spots like Gibbon Anchorage. The map records a specific moment in the mid-20th century before later revisions, preserving the exact locations of tidal benchmarks like BM 3 used for charting these Alaskan waters.
