1948 Map of Petersburg A-6

USGS Topo · Published 1957

About this map

Sumner Strait dominates this maritime survey, separating the eastern shore of Kuiu Island from the northern reaches of Kosciusko Island within the Tongass National Forest. The map, compiled from mid-century aerial photography and hydrographic charts, illustrates a complex archipelago of hazards and harbors. Of particular interest to historians are the remote landmarks along the coastline, such as Ruins Pt and Louise Cove. The interior terrain is defined by steep contours and unmapped elevations, while the shoreline is punctuated by numerous unnamed islets and specific navigational points like Pt St Albans and Pt Amelius. The presence of Calder Rks and the Barrier Islands highlights the intricate navigation required in these Alaskan waters during the late 1940s.
