1951 Map of Petersburg A-6

About this map

Sumner Strait dominates this maritime survey, separating the eastern shores of Kuiu Island from the northwestern coastline of Kosciusko Island. The map documents a landscape within the Tongass National Forest where the primary features are defined by their relationship to the sea. Navigation and coastal geography are the focus, with prominent landmarks such as Pt Amelius and Point St Albans anchoring the western coastline. The intricate shoreline of Kosciusko Island is marked by small freshwater inflows like Trout Creek and Charley Creek. The presence of Ruins Pt and various survey resets like Albans Reset suggests a history of coastal mapping and possibly early navigation aids or temporary camps. This 1951 record, revised in the early 1990s, provides an essential look at the Alexander Archipelago's waterways before more modern digital updates.
