1955 Map of Mount Hayes B-3

About this map

Gerstle Glacier and its massive neighbor Johnson Glacier dominate this mid-century topographic survey of the interior Alaskan mountains. The landscape is defined by vast ice fields and high-altitude drainage patterns, with the map documenting the intricate network of crevasses that scar the glacial surfaces. The survey captures the natural divide formed by the crest of the range, where ice flows south into the Gulkana Glacier and Gakona Glacier or west toward the Canwell Glacier. This frozen frontier serves as the administrative border between the Fourth Judicial Division and the Third Judicial Division, illustrating how Alaska’s early territorial boundaries were often drawn along the inaccessible spines of its highest peaks during the mid-1950s.
