2017 Map of Sumdum D-4 NW
USGS Topo · Published 2017About this map
Tracy Arm cuts deeply into the glacier-carved landscape of Southeast Alaska within this 2017 survey. The fjord is dominated by the massive Sawyer Glacier at its eastern terminus, where ice meets the marine waters of the Tongass National Forest. The map shows a terrain of steep, high-elevation contours and glacial features, including the small, isolated Sawyer Island positioned near the glacier's face. The lack of roads or infrastructure highlights the protected wilderness character of the Tongass National Forest boundaries in this remote coastal corridor. Topographic lines reveal the dramatic verticality of the surrounding peaks that frame the narrow waterway, documenting the ongoing interaction between ice and sea in the Hoonah-Angoon Census Area.
