2021 Map of Ketchikan B-4 SW
USGS Topo · Published 2021About this map
Thorne Arm dominates the landscape of this 2021 survey, a deep waterway flanked by the dense timberlands of the Tongass National Forest. The map details a labyrinthine coastline of inlets and points, including Coho Cove and Gnat Cove to the west, and the protected waters of Moth Bay further south. While largely a wilderness area, the terrain is marked by significant peaks and ridges like Notch Mtn and Alava Ridge, reflecting the steep ascent from the shoreline to the inland mountains.
