1961 Map of Skagway A-6

About this map

Glacier Bay National Monument dominates this mid-century survey, centering on the deep waters of Tarr Inlet where it meets the face of the Margerie Glacier. The map documents a stark landscape of ice and stone along the international border, where the Canada United States boundary is defined by high-altitude points including Mt Forde and Boundary Peak 161. To the northeast, the Rendu Glacier flows toward the coast from the slopes of Mt Barnard. This topography, based on aerial photographs from 1948 and 1954, captures the exact position of these massive ice flows and the intricate network of crevasses that defined their surfaces during the early 1960s. It serves as a precise record of glacial extent and maritime depth data compiled by the Usc&GS before more modern shifts in the shoreline.
