1955 Map of Mt. Hayes C-3

About this map

Mount Hajdukovich anchors the southern portion of this high-altitude landscape, where the massive Gerstle Glacier descends toward the lowlands. The ice field is marked by numerous Crevasses, indicating a dynamic glacial environment during the mid-1950s. As the ice melts, it feeds the wide, braided channel of the Gerstle River, which dominates the central valley. North of the river, Granite Mountain rises sharply, its slopes drained by several named streams including Granite Creek and McCumber Creek. This 1955 survey captures a roadless wilderness in the Alaska Range, where the only passage through the high peaks is marked by points like St Anthony Pass. The map serves as a primary record of glacial extent and alpine drainage patterns, including smaller tributaries like Little Gerstle River and Pegmatite Creek, before modern climatic shifts significantly altered these northern ice sheets.
