1958 Map of Iliamna D-2

USGS Topo · Published 1981

About this map

The Chigmit Mountains dominate this region of the Kenai Peninsula Borough, where steep peaks and glacial systems define the drainage patterns of the Alaskan wilderness. Based on 1957 aerial photography and 1958 field annotations, the map shows the transition from high-altitude features like Roscoe Glacier and Roscoe Peak down to the tidal flats of Iniskin Bay. Significant river systems, including the Pile River, Iliamna River, and Iniskin River, carve deep valleys through the range, while Three Sisters Mountain serves as a prominent landmark in the western interior. Near the coast, the topography softens into the sediment-rich areas of Mud and Sugarloaf Mountain, reflecting the dynamic environment where mountain runoff meets the sea.
