About this map

The Glacier Bay National Monument dominates this coastal Alaskan landscape, where the ice-dominated geography of the Fairweather Range meets the deep waters of the Pacific. At the heart of the sheet, Johns Hopkins Inlet serves as the terminus for a massive network of ice flows, most notably the Johns Hopkins Glacier and the Margerie Glacier. These frozen rivers are fed by high-altitude snowfields surrounding peaks like Mt Turner on the international boundary and Mount Abbe to the south.

The map captures a specific state of the glacial retreat as it was recorded in the early 1960s. The intricate network of tributary glaciers, including Topeka Glacier, Toyatte Glacier, and Katlachan Glacier, illustrates a highly complex topographic environment. The presence of numerous crevasses marked throughout the higher elevations indicates the active movement of these ice sheets during this period of the mid-twentieth century.
