2021 Map of Sumdum D-4 NW

USGS Topo · Published 2021

About this map

Tongass National Forest dominates the landscape of this coastal Alaskan region, where steep glacial topography meets the saltwater of Tracy Arm. The map documents a dramatic glacial environment, specifically the terminus area of the Sawyer Glacier and the adjacent Sawyer Island. This 2021 survey provides a high-resolution view of the interaction between ice and sea, showing the complex contouring of the fjord's walls as they descend into the narrow waterway. The absence of human-built infrastructure highlights the remote and protected nature of this wilderness area within the Hoonah-Angoon Census Area, preserving a detailed record of the shoreline and ice positions as they existed during the early twenty-first century.
