2017 Map of Sitka C-7 NW

About this map

Tongass National Forest blankets the intricate island chains and narrow waterways of the Alexander Archipelago on the outer coast of Chichagof Island. This survey highlights the complex maritime geography of the Gulf of Alaska shoreline, where deep inlets like Portlock Harbor and Didrickson Bay penetrate the land. Larger landmasses such as Hogan Island and Herbert Graves Island are separated by treacherous coastal waters including Imperial Passage and South Passage. The map documents the numerous hazards and landmarks essential for coastal navigation, such as the White Sisters and the Myriad Islands south of Kukkan Bay. Unlike interior regions, this landscape is defined almost entirely by its tidal reaches and rocky outcrops like Ittar Rock and Minnie Reef, providing a detailed view of the coastal wilderness within the Sitka Borough.
