1954 Map of Iditarod D-6

About this map

The Netletna River flows through this interior Alaskan wilderness, as documented by photogrammetric methods in the mid-1950s. The landscape is defined by the meandering courses of the Big Yetna River and Little Yetna River, creating a complex network of wetlands and seasonal waterways typical of the Yukon-Koyukuk region. This 1954 survey captures the terrain long before modern federal land designations were finalized, though this edition later includes the boundaries for the Innoko National Wildlife Refuge and the Innoko Wilderness. The lack of named settlements or man-made structures emphasizes the untouched nature of this remote river system, where the North Boundary Seward Meridian serves as one of the few formal geographic reference points in a region dominated by hydrological features.
