1948 Map of Mount Fairweather D-1

About this map

Glacier Bay National Monument dominates this mid-century survey, revealing a landscape defined by retreating ice and advancing waterways. The glacial network is highly active, with the massive Muir Glacier at the north feeding into the expanding Muir Inlet. The map documents numerous ice fields including the Burroughs Glacier, Idaho Glacier, and Casement Glacier, which carve through high-elevation features like Minnesota Ridge and Mt Kloh Kutz. This 1948 topography, based on aerial photography, captures the exact state of the inlets and ice fronts before further decades of warming. Coastal features such as Sebree Island and the Caroline Shoal at the southern end of the inlet provide essential markers for understanding the shifting shoreline and maritime navigation within the bay.
