2021 Map of Sumdum C-4 NW

USGS Topo · Published 2021

About this map

Endicott Arm defines the southern coastline of this coastal terrain within the Tongass National Forest. The map documents a rugged landscape dominated by steep glacial valleys and high ridges, where the boundary between the Hoonah-Anggoon Census Area and Petersburg Borough cuts through the northeast corner. This 2021 survey reveals a territory almost entirely defined by its natural topography rather than human infrastructure, showing the intricate interplay of elevation and tidewater. The detailed contour lines illustrate the sharp rise from the shoreline of Endicott Arm to the interior peaks, providing a clear view of the drainage patterns and glaciated landforms that characterize this portion of Southeast Alaska.
