1954 Map of Iliamna C-4

About this map

Iliamna Lake dominates the northern landscape of this mid-century survey, its expansive waters giving way to several prominent islands and indented bays. The topographic detail, mapped by the Army Map Service, focuses on the drainage systems feeding into the lake, most notably the meandering course of the Copper River as it flows toward Intricate Bay. This water-connected wilderness is defined by the proximity of high-altitude basins like Upper Copper Lake and Lower Copper Lake, which feed the river system from the east.
