1948 Map of Petersburg C-6

USGS Topo · Published 1981

About this map

Kuiu Island and Kupreanof Island dominate this topographic study, separated by the intricate maritime corridor of Rocky Pass. This 1948 survey, based on aerial photography, documents the complex shoreline of the Tongass National Forest before modern developments. The geography is defined by narrow waterways and sheltered inlets like Seclusion Harbor and Salt Lagoon, which suggest the historical reliance on small-craft navigation for accessing the interior of these islands. The presence of named maritime hazards and landmarks such as Devils Elbow and The Summit highlights the essential nature of coastal piloting in the Alexander Archipelago. Farther south, the expanse of Three Mile Arm and the isolated Monte Carlo Island illustrate a landscape of dense timber and tidal flats, largely untouched by road networks or permanent settlements during the mid-century era.
