About this map

Baranof Island is the central focus of this coastal survey, where the dense wilderness of the Tongass National Forest meets the deep inlets of the Alexander Archipelago. The landscape is dominated by steep glacial valleys and a complex network of freshwater basins, including Antipatr Lake in the north and Ludvik Lake near the southern coast. These alpine and coastal waters are connected by narrow fjords such as Port Herbert, which cuts deeply into the island's eastern flank.

The settlement pattern is defined by the geography, with habitable land found primarily around the protected waters of Port Walter and the southern Big Branch Bay. Inland, the terrain remains largely untouched, characterized by high-elevation lakes like the Rostislaf Lakes and Lake Osprey. The map serves as a detailed record of the island's natural drainage and coastal profile, illustrating the relationship between the mountainous interior and the intricate shoreline of Southeast Alaska.
