1951 Map of Seward A-3

About this map

Latouche Island and the surrounding Prince William Sound waterways reveal a landscape of industrial extraction and maritime commerce in the early 1950s. The presence of the Beatson Mine (Aband) and Blackbird Mine (Aband) near the Wilson River indicates the region's historical reliance on mineral wealth, while the San Juan Cannery on Evans Island highlights the vital role of the fishing industry. Deep channels like Knight Island Passage and Montague Strait frame the rugged terrain of Bainbridge Island and Flemming Island. Surveyed shortly after mid-century, the map also identifies critical navigational and infrastructure points such as the Seaplane Base at Thumb Bay and the Lighthouse Reserve on the eastern shore, providing a clear picture of how aviation and maritime travel supported these remote coastal outposts.
