2021 Map of Port Alexander B-4 NE
USGS Topo · Published 2021About this map
Tongass National Forest dominates the upper right corner of this coastal sheet, where the mountainous terrain of the Alexander Archipelago meets the open sea. While the vast majority of this 2021 survey covers the deep waters of the Gulf of Alaska, the eastern edge provides a detailed topographic record of the island coastline within the Sitka city and borough. The map illustrates the sharp transition from steep, forested slopes to the sea, reflecting the rugged character of this maritime region. Geodetic lines for t62s r66e, t62s r67e, and t63s r67e establish the Public Land Survey System grid across the expanse, providing a precise framework for marine and wilderness navigation in Southeast Alaska.
