About this map

Revillagigedo Island dominates this coastal landscape within the Tongass National Forest, showcasing the intricate waterways and maritime boundaries of Southeast Alaska. The map traces the rugged coastline from California Head and California Cove in the north down to the southern reaches near Bold Island. A significant administrative divide is marked by the Ketchikan Gateway Borough Prince of Wales-Hyder Census Area boundary, which cuts through the waters of Thorne Arm.

Inland, the topography rises sharply toward Black Mtn, while the Annette Island Reserve occupies the southwestern portion of the sheet. Modern infrastructure is represented by the South Tongass Highway skirting the western shore, providing a vital connection along the coast. Smaller features like Trap Lake and Coho Cove highlight the isolated pockets of freshwater and sheltered anchorage that characterize this part of the Alexander Archipelago.
