1954 Map of Mount McKinley A-1

About this map

Mt McKinley National Park dominates this mid-century topographic study, showcasing a landscape defined by massive ice flows and high-altitude peaks. The survey, based on 1954 aerial photography and field annotation, documents the sweeping expanse of the Eldridge Glacier as it moves through the southern portion of the quadrangle. High-altitude points such as Mount Mather and Mount Eldridge serve as primary landmarks amidst a network of intricate contour lines and numerous crevasses that mark the glacial surfaces. In the northwest corner, the Muldrow Glacier is visible, illustrating the complex drainage patterns of this portion of the Alaska Range. This map captures the park's interior before significant modern infrastructure, providing a baseline for glaciologists and alpine historians tracking the movement and state of these iconic ice fields during the mid-1950s.
