About this map

The Kvichak River and Alagnak River dominate this 1951 landscape, weaving through a complex network of wetlands and small lakes in southwest Alaska. The terrain is characterized by low-lying tundra and expansive marshlands, with occasional elevations marked by triangulation stations such as Vabm 408 Yenuk, Vabm 361 Statem, and Vabm 197 Naku. These peaks serve as critical reference points in an otherwise fluid and shifting environment.

Mapped via photogrammetric methods from aerial photographs, this document reveals a region entirely devoid of roads or trails during the mid-century period. The intricate drainage patterns and myriad unnamed ponds illustrate the raw hydrology of the Bristol Bay drainage basin. It provides a foundational look at the unsurveyed and unmarked land lines as they were predetermined by the Bureau of Land Management before modern development.
