1994 Map of Sumdum A-6

About this map

Kupreanof Island defines the southern half of this coastal survey, where the dense timber of the Tongass National Forest meets the cold waters of the Alexander Archipelago. Mapping here reveals a landscape shaped by both natural features and industrial extraction, marked by numerous pits and topographic points like Turn Mountain and Slate 2. The northern waters of Frederick Sound serve as a primary maritime corridor, traced by the Alaska Marine Highway and guarded by the Lighthouse Reserve on Turnabout Island. To the southwest, the passage narrows into the Keku Strait, while Gunnuk Creek drains the interior elevations. This edition reflects the mid-1990s character of the Petersburg Ranger District, balancing maritime navigation with the resource extraction and forest management typical of the region's wilderness economy.
