1951 Map of Seward B-4

About this map

Sargent Ice Field dominates the western interior of this coastal Alaskan landscape, feeding a massive network of ice including the Princeton Glacier and Chenega Glacier. This mid-century survey captures the complex glaciology and deep-water inlets of western Prince William Sound before more recent decades of glacial retreat. The maritime geography is defined by deep incisions like Blue Fiord and Nassau Fiord, which reach toward the ice fields. To the east, the landscape transitions to the complex island and lake systems of Dangerous Passage, featuring Chenega Island and the interconnected Jackpot Lakes. Numerous triangulation stations, such as VABM Duke and VABM Icy, indicate the precision of the mapping effort across this roadless portion of the Chugach National Forest.
