About this map

Pedro Bay and Pile Bay indent the northeastern shoreline of Iliamna Lake in this mid-century topographical record. The landscape is dominated by the water systems that define the region, including the Copper River and its connection to Lower Copper Lake and Upper Copper Lake. A cluster of significant islands, notably Porcupine Island, Flat Island, and Triangle Island, are charted in detail across the lake's surface.
