About this map

Sutwik Island and the neighboring Semidi National Wildlife Refuge anchor this mid-century reconnaissance study of the Alaska Peninsula’s southeastern coast. The shoreline is characterized by deep glacial indentations and rugged volcanic topography, where the Aniakchak River drains toward the Pacific Ocean from the interior. The landscape is a complex network of coastal features, including the notable Meshik Lake and prominent peaks like Pinnacle Mtn.

Maritime navigation is the primary focus, with detailed soundings and hazardous features documented throughout Chignik Bay and Amber Bay. Remote outposts and landmarks like the Aiugnak Columns and Foggy Cape serve as critical reference points in an era before modern infrastructure reached these reaches of the Third Judicial Division. The map provides a detailed look at the drainage patterns of Yantarni Creek and Wiggly Creek, illustrating the raw hydrology of the Aleutian Range.
