1961 Map of Mount Fairweather D-7

About this map

Glacier Bay National Monument borders the rugged coastline where the Pacific Ocean meets the northern reaches of the Gulf of Alaska. This 1961 field-annotated survey captures a landscape dominated by the advancing and retreating ice of the Grand Plateau Glacier, which flows toward the sea in the northeastern corner of the map. The cartography highlights an Indefinite Boundary along the monument's edge, reflecting the shifting nature of this coastal wilderness before more modern shoreline surveys were finalized. Depth soundings across the marine areas provide a detailed look at the underwater topography of these glacial waters, recorded just as photogrammetric methods from 1948 aerial photography were being integrated into the official record of this remote Alaskan territory.
