1948 Map of Sumdum B-4

USGS Topo · Published 1974

About this map

Washington Peak towers over a complex landscape of glacial inlets and tidal waterways in this mid-century survey of the Tongass National Forest. The map is dominated by the expansive Port Houghton and its North Arm, where the topography transitions sharply from high alpine ridges down to a sprawling Tidal Flat. A solitary Cabin on Walter Island represents the only named man-made structure in this coastal wilderness, suggesting the isolated nature of the area's early human footprint.
