1960 Map of Atlin A-7

About this map

Mt Poletica stands as a primary high point along the international divide in this 1960 survey of the Alaskan wilderness near the Canadian border. The landscape is defined by its extreme glacial features and high-altitude surveying markers, including Boundary Peak 103, Boundary Peak 101, and Boundary Peak 102. This map, based on 1948 aerial photography and 1960 field annotation, serves as a record of the trans-border region where the United States Canada line follows a series of jagged summits. The presence of numerous Crevasses across the ice fields emphasizes the volatile nature of the terrain, while the sparse nomenclature reflects an area almost entirely devoid of permanent human settlement or infrastructure during the mid-20th century. Local boundaries for T. 32 S. and R. 65 E. are projected across the ice, though the margin notes these locations remained unsurveyed and unmarked at the time.
