1954 Map of Ophir A-6

About this map

Innoko River and Iditarod River dominate this low-lying Alaskan landscape, their meandering courses creating a complex network of oxbow lakes and wetlands. The terrain is characterized by a dense pattern of water bodies and marshland, highlighting the dynamic hydrology of the Yukon-Koyukuk region before any modern infrastructure altered the drainage. The Kateel River Meridian bisects the area, serving as a primary surveying reference for this remote wilderness. Aside from the natural water features, the landscape remains largely devoid of named settlements, with only the VABM Rod benchmark providing a fixed point of triangulation for early mappers. This map illustrates the intricate, shifting nature of subarctic river systems in an era when aerial photogrammetry was first being used to document the interior's vast, roadless expanses.
