1954 Map of Iliamna D-8

About this map

Koktuli River dominates this southwestern Alaskan landscape as it was documented in the mid-1950s. The topographic detail, produced by the U.S. Geological Survey and the Army Map Service, captures a complex system of drainage and marshy lowlands surrounding the main river channel. The river's winding path serves as the central artery for this remote region, where the terrain is defined by dramatic elevation changes and a network of unnamed tributaries. To the southeast, the labeling of Kaskunuk provides a rare point of reference in an otherwise unsettled expanse. The map reflects a period of intensive aerial survey and photogrammetry, illustrating the glacial and fluvial processes that shaped this wilderness before modern infrastructure reached the interior.
