2021 Map of Sumdum C-4 SE

About this map

Tongass National Forest covers the majority of this coastal wilderness, where the high ridges of the Coast Mountains meet the tide-influenced waters of Southeast Alaska. This 2021 topographic record reveals a landscape dominated by dramatic elevation changes, rising from the shoreline to over 5,000 feet within just a few miles. The northern portion of the map is defined by the massive North Dawes Glacier, which serves as a critical point of study for glacial retreat and geological transformation. The map provides precise detail on the intersection of maritime and glacial environments, documenting the complex contours of the fjords and the vast protected lands managed by the forest service. For those studying the glaciology of the region, the placement and extent of the ice fields relative to the coastline offer significant insight-gain into the modern state of Alaska's wild interior.
