1992 Map of Petersburg C-3 SW

About this map

Mitkof Island serves as the central anchor of this Southeast Alaska coastal study, dominated by the heavily timbered reaches of the Tongass National Forest. The geography is defined by the vital maritime passage of the Wrangell Narrows, where intricate reefs and points such as Point Lockwood and December Point dictate the navigation of the Inside Passage. Along the western edge, the map details the fragmented shorelines of Kupreanof Island and the Lindenberg Peninsula, separated by the Keene Channel.
