2018 Map of Sumdum B-3 SE
USGS Topo · Published 2018About this map
Tongass National Forest encompasses this high-altitude Alaskan landscape, where the massive ice fields of the Coast Mountains define the physical geography. The sheet is dominated by the glacial reach of the Dawes Glacier and North Arm Glacier, illustrating the complex drainage patterns and ice-carved topography of the Petersburg Borough region. Unlike many maps of the period that emphasize human settlement, this survey reveals a primitive wilderness characterized by dramatic elevation changes, ranging from sea-level inlets to the prominent peak of Hump Knoll. The technical detail of the ice contours provides an invaluable record for understanding the glaciology of this corner of Southeast Alaska as it appeared in the early twenty-first century.
