2017 Map of Sumdum A-5 SW

About this map

Kupreanof Island occupies the southern half of this coastal survey, where the northern slopes of the Bohemian Range meet the sea. This landscape is almost entirely defined by the protected wilderness of the Tongass National Forest, showing a roadless expanse of wetlands and steep coastal terrain. To the north, the deep waters of Frederick Sound separate the island from the mainland, marking a significant maritime passage within the Alexander Archipelago. The map captures the boundary between the Petersburg Borough and the Prince of Wales-Hyder Census Area, which cuts across the sound. This 2017 edition provides a modern topographic record of the island's primitive character, where land use is governed by federal forest management rather than urban settlement.
