About this map

Chenega Glacier and Tigertail Glacier dominate the northern terrain of this coastal Alaskan landscape, where the ice meets the complex inlets of Icy Bay and Whale Bay. Within the Chugach National Forest, the map traces a wild maritime environment defined by steep peaks like Claw Peak and intricate waterways. This mid-century survey reveals the untouched geography of Bainbridge Island, separated from the mainland by the Bainbridge Passage.

The presence of the Bainbridge Glacier descending toward the coast highlights the dramatic elevation changes that characterize this subarctic shoreline. Researchers can identify coastal features such as Procession Rocks and Goat Harbor, along with the deep waters of Port Swanson. The mapping of soundings and glacial extents provide a record of these glacial fjords before modern climate shifts altered the ice-to-water boundaries.
