2017 Map of Juneau D-4 NW

About this map

Lynn Canal dominates this coastal survey, serving as a primary maritime thoroughfare through the Inside Passage of Southeast Alaska. The map highlights the maritime hazards and natural shelters critical to navigation in these glacial waters, specifically centering on the narrow landforms of Sullivan Island and the isolated Eldred Rock. On the western shore, Rescue Harbor provides a rare point of protected anchorage along the island's jagged coastline, while the vast expanse of the Tongass National Forest blankets the surrounding mountain slopes. The boundary line between Haines Borough and Juneau Borough cuts across the deep waters of the canal, marking a significant administrative division in this largely roadless wilderness. This 2017 edition documents the shoreline and topography as recorded by the U.S. Geological Survey, showcasing the relationship between the sea and the Tongass timberlands.
