2017 Map of Ketchikan A-4 SW

About this map

Mary Island and Cat Island dominate this coastal survey of the Alexander Archipelago, illustrating the maritime character of the Tongass National Forest in Southeast Alaska. The map highlights the essential navigational features of the era, from protected waters like Customhouse Cove and Mary I Anchorage to the hazardous Bostwick Reef and Danger Passage. These islands are separated by the Felice Strait, a vital corridor for regional travel. Small landforms such as Village Island, Fripo Island, and Bird Island dot the surrounding waters, while Grave Point and Saw Ridge provide prominent landmarks for those traversing the Gulf of Alaska. The presence of labels like Point Winslow and Edge Point suggests a history of maritime surveying focused on securing safe passage through these dense island clusters and tidal channels.
