2017 Map of Bradfield Canal B-6 SW

About this map

Tongass National Forest dominates the landscape of this 2017 survey, where the saltwater corridor of Blake Channel separates the mainland from the southeastern edge of Wrangell Island. This portion of the Alexander Archipelago is defined by sharp elevation changes rising from the Gulf of Alaska to peaks over 3,000 feet. The map documents a complex system of drainage and freshwater bodies including Marten Lake, Marten Lake, and the smaller Clay Lake tucked into the eastern ridges. Notable landmarks along the coastline include Capel Point, which provides a navigational reference for the waterway. Small streams such as Oerns Cr and Marten Cr feed the larger lakes, illustrating the hydrological patterns of the coastal rainforest before the terrain transitions into the high-alpine interior.
