1951 Map of Seward A-2

About this map

Montague Strait dominates this maritime survey, serving as a deep-water passage between the northern reaches of Montague Island and the rugged southern tip of Knight Island. The topography reflects a landscape of dramatic coastal relief, where Horn Mountain rises sharply above the waters of Hogan Bay and Snug Harbor. This 1951 photogrammetric record captures the uninhabited character of the Chugach National Forest at mid-century, mapping critical navigational landmarks such as The Needle and Discovery Pt. The hydrographic data, compiled from USC&GS charts, provides detailed soundings through the main Channel and around the smaller landmasses of Green Island and Little Green Island. This specific configuration of the shoreline and seabed predates the significant tectonic shifts caused by the 1964 earthquake, making it a vital baseline for understanding the coastal evolution of this Prince William Sound corridor.
