About this map

Catherine Island dominates this maritime survey, situated at the complex intersection of Peril Strait and Chatham Strait within the Tongass National Forest. The map reveals a labyrinthine coastline of the Alexander Archipelago, where the deep waters of Kelp Bay separate Catherine Island from the northern reaches of Baranof Island. To the north, the southern tip of Chichagof Island is marked by Sitkoh Bay and Florence Bay.

Navigation and coastal life are centered around narrow waterways like Thatcher Channel and protected inlets such as Portage Arm. Sparse human presence is indicated by Cabins located near Traders Is, suggesting seasonal or subsistence use of the rich marine environment. The intricate hydrography, featuring hazards like Morris Reef and Zubof Rk, underscores the seafaring nature of this region during the mid-twentieth century.
