2021 Map of Sumdum B-3 NE
USGS Topo · Published 2021About this map
Dawes Glacier dominates this high-altitude landscape in the southeastern reaches of Alaska, where the ice and rock of the Tongass National Forest define the coastal topography. This 2021 topographic record captures the complex glacial contours and steep elevations of the Coast Mountains, illustrating the massive ice sheet as it carves through the bedrock. The map is primarily a study of glaciology and wilderness, showing the intricate drainage patterns and vertical rise of the terrain without the presence of human infrastructure or roads. It serves as a precise baseline for researchers and geologists monitoring the movements of one of the region's prominent glaciers within the protected boundaries of the nation's largest national forest.
