2017 Map of Sumdum B-5 NE

About this map

Hobart Bay dominates this coastal survey, where the saltwater environment of the Tongass National Forest meets the steep topography of Southeast Alaska. This 2017 study illustrates the intricate interface of land and sea, marked by significant navigational landmarks such as Entrance Island and Point Hobart. The tidal complexities of the region are evidenced by the presence of The Salt Chuck in the northeastern corner, a term often used in the Pacific Northwest for a saltwater body or lagoon affected by the tides. Freshwater drainage from the high inland terrain is channeled through systems like Libby Cr, which cuts through the dense forest before reaching the coastline. The map serves as a contemporary record of this largely undeveloped maritime landscape within the Petersburg Borough.
