USGS Topo · Published 1958About this map
Glacial carvings and deep fjords define this portion of the Tongass National Forest along the mainland coast. The prominent Port Houghton serves as the primary waterway, branching into the Walter Island Arm and leading toward a significant Tidal Flat. High-altitude surveying points like VABM 5188 Triple C and Washington Peak mark the steep elevations that rise abruptly from the sea.
