1954 Map of Ophir A-4

About this map

The Iditarod River meanders through a vast expanse of wetlands and low-relief terrain in this mid-century survey of the Alaska interior. The landscape is characterized by a stark division between the intricate, waterlogged patterns of the western basin and the rising elevations to the east. Topography by the U.S. Geological Survey reveals isolated high points such as Chick and Lonesome, which stand as significant landmarks in an otherwise feature-sparse wilderness. The mapping represents a transition in cartographic technique, utilizing photogrammetric methods from aerial photographs taken between 1953 and 1955. This specific quadrangle captures a moment before modern infrastructure, where the natural drainage of the river system dictated the only navigable routes through the region.
