Tongass National Forest encloses this wilderness landscape where glacial runoff and alpine summits define the geography. The high peaks of the Cosmos Range and the Patterson Peaks dominate the northern terrain, with Pirate Peak standing as a central landmark. Water is the primary architect here, from the branching flow of the Patterson River and Muddy River to the high-elevation waters of Ruth Lake and Ess Lake.
