1960 Map of Anchorage C-3

About this map

Mount Sergeant Robinson anchors this high-elevation Alaskan wilderness in the Chugach Mountains, standing as a prominent landmark amidst a landscape defined by active ice and glacial runoff. The topography, mapped via aerial photography in 1957 and field-annotated in 1960, reveals a complex network of glacial flows and high-altitude drainage systems. Water from Glacier Creek and Monument Creek carves through the terrain, illustrating the constant movement of ice and water in the Matanuska-Susitna region. A distinctive technical detail on this sheet is the notation of Crevasses, providing a rare topographic record of the specific hazards and glacial conditions present during the late 1950s. These markings offer researchers a baseline for studying the shifting nature of the Alaska range before modern satellite monitoring, captured at a time when much of the land remained unsurveyed and unmarked by formal land lines.
