1948 Map of Petersburg C-6

About this map

Kuiu Island and Kupreanof Island dominate this coastal survey, separated by the intricate and islet-choked passage of Rocky Pass. Entirely contained within the Tongass National Forest, the landscape is defined by deep maritime inlets like Port Camden and the elongated Threemile Arm. The topography transitions from these tidewaters to significant elevations such as The Summit, reflecting a wilderness state largely untouched by permanent road infrastructure during the late 1940s. Water-based navigation is the primary focus, with detailed soundings and navigational hazards identified at Devils Elbow and around the numerous small islands like Monte Carlo Island and Eagle Island. The presence of secluded waters like Salt Lagoon and Seclusion Harbor suggests the isolation of the Alexander Archipelago before modern development reached these remote Alaskan shores.
