About this map

The Harding Ice Field dominates the southeastern portion of this 1950s survey, a massive glaciated expanse that feeds several prominent ice flows across the Kenai Peninsula. The map provides a meticulous record of this frozen landscape before significant modern climatic shifts, documenting the precise extent of the Skilak Glacier, Killey Glacier, and Indian Glacier. These ice bodies descend from the high field into deep valleys, where the Killey River originates near Upper Killey Lake.

Much of the western terrain is protected within the Kenai National Moose Range, characterized by sharp elevation changes and high peaks like VABM 4782 Killey. Surveyors noted numerous crevasses and technical hazards across the ice, marking a wilderness defined by its glaciology rather than human settlement. The Seward Base Line runs through the center of the sheet, providing a vital cadastral reference point for early Alaskana mapping.
