1958 Map of Iliamna D-1

About this map

Chinitna Bay dominates this coastal Alaska landscape, carving into the Iniskin Peninsula where the waters meet the mudflats of the Chinitna River. The terrain is defined by massive ice features like Umbrella Glacier and West Fork glacier, which feed a network of braided streams including Silver Salmon Creek and Beaver Creek. High peaks such as South Twin and North Twin overlook deep valleys and active Crevasses.
