2021 Map of Sitka B-5 NW

USGS Topo · Published 2021

About this map

Chichagof Island terrain dominates this coastal study, where the intricate waterways of the Tongass National Forest meet the Gulf of Alaska. The map documents a complex maritime landscape defined by narrow passages and hazardous shoals, including the strategically critical Peril Strait and the churning waters of Sergius Narrows. These channels have long served as vital corridors for navigation through the Alexander Archipelago, where tidal currents necessitate precise knowledge of features like Rapids Island and Liesnoi Shoal.
