2018 Map of Sumdum B-3 NE

About this map

Dawes Glacier dominates this landscape within the vast protected boundaries of the Tongass National Forest. This 2018 topographic survey illustrates the sheer scale of the ice field as it carves through the mountains of the Petersburg Borough. The map provides a precise record of the glacier's extent and the surrounding ice-scoured terrain, where massive elevation changes are documented by dense contour lines. This is a wilderness defined by its glaciated valleys and the absence of any established roads or human settlements, highlighting the remote character of Southeast Alaska's coastal range.
