1954 Map of Iditarod D-6

USGS Topo · Published 1983

About this map

The Netletna River serpentines through a complex hydrological landscape in this mid-century survey of the Alaska interior. The area is dominated by the extensive wetlands of the Innoko National Wildlife Refuge, where the terrain is characterized by intricate drainage patterns and low-relief marshlands. Within the refuge lies the Innoko Wilderness, a protected expanse that preserves the natural state of this subarctic ecosystem. The confluence and divergence of the Big Yetna River and Little Yetna River in the eastern portion of the map reveal a shifting river-and-wetland network that remains largely untouched by permanent settlement or infrastructure. This topography, compiled from aerial photography taken in 1953, serves as a record of the remote wilderness before the establishment of modern conservation boundaries and minor 1980s revisions.
