About this map

Duncan Canal defines the central axis of this coastal wilderness, a deep waterway separating the Lindenberg Peninsula from the primary mass of Kupreanof Island. Surveyed in the mid-twentieth century within the Tongass National Forest, the map reveals a landscape defined by tidewater complexity, from the sprawling Tidal Flat at the mouth of Mitchell Slough to the intricate cluster of the Castle Islands.
