1951 Map of Dillingham A-1

About this map

Kvichak River and the meandering Alagnak River dominate this 1951 snapshot of the Alaska Peninsula, a landscape defined by intricate water networks and low-lying wetlands. At a time when much of the region remained unsurveyed and unmarked on the ground, these topographic surveys relied heavily on photogrammetric methods from aerial photographs. The terrain is punctuated by significant vertical control points, including VABM 408 Yenuk and VABM 361 Statem, which served as the primary terrestrial anchors in a territory without established roads or trails. This map documents a period before modern infrastructure reached this part of Lake and Peninsula, capturing the raw hydrology of the river systems as they were interpreted by the Geological Survey in the mid-twentieth century.
