2021 Map of Port Alexander B-3 SW
USGS Topo · Published 2021About this map
The Gulf of Alaska dominates the western half of this coastal landscape, where the open sea meets the intricate shoreline of the Tongass National Forest. The map documents a rugged archipelago environment within the Sitka City and Borough, defined by steep topography and heavy timber. Inland, Tumakof Lake sits at the northern edge of the sheet, providing a rare freshwater landmark amidst the jagged inlets and peninsulas of the Alexander Archipelago. This 2021 update from the U.S. Geological Survey focuses on the natural hydrology and boundaries of the Tongass National Forest, showing a landscape where human infrastructure is entirely absent in favor of protected wilderness and complex tidal interfaces.
