2017 Map of Ketchikan A-4 NW
USGS Topo · Published 2017About this map
Annette Island Reserve and the southern reaches of Tongass National Forest dominate this coastal landscape, where the waters of the Gulf of Alaska meet the intricate shorelines of the Alexander Archipelago. The map provides a detailed view of the maritime boundary between the Ketchikan Gateway Borough and the Prince of Wales-Hyder Census Area, cutting through the passage near Hog Rocks. Significant coastal topography is noted along the southern edge of Revillagigedo Island, including the steep elevations of Saw Ridge and Alava Ridge overlooking the entrance to Thorne Arm. This nautical-facing survey highlights numerous navigational landmarks essential to Southeast Alaska's maritime history, from the prominent Cone Point and Point Alava to smaller landmasses like Walker Island, Ham Island, and the isolated Twin Islands.
