1951 Map of Seward D-1

About this map

Glacier Island dominates the central waters of this maritime survey, acting as a natural breakwater between the open expanse of Prince William Sound and the intricate coastline to the north. The map documents a complex glacial landscape where Columbia Bay and Heather Bay meet the sea, defined by deep-water passages and numerous small harbors such as Irish Cove and Finski Bay. A notable cartographic detail is the convergence of the Seward Meridian and Copper River Meridian, which slice through the western edge of Glacier Island.
