1948 Map of Petersburg B-6

About this map

Kuiu Island dominates this mid-century maritime survey, revealing a landscape of intricate shorelines and critical navigational aids within the Alexander Archipelago. Coastal life is marked by isolated Cabins and the essential Beauclerc Light at the southern entrance to Port Beauclerc. The map documents the complex hydrography of the region, where the sheltered waters of Alvin Bay and Reid Bay meet the expansive Sumner Strait and Keku Strait. These waterways served as the primary thoroughfares for the local fishing and timber economies, punctuated by hazards like Mariposa Reef and Calder Rocks. At the southern end, the terrain rises sharply to Beauclerc Peak, providing a dramatic backdrop to the small islands such as Edwards Island and Beauclerc Island that guard the coastal inlets.
