1954 Map of Ophir A-5

About this map

The Iditarod River meanders across this interior landscape, forming an intricate network of oxbows and sloughs that define the region's hydrology. This mid-century survey by the Usgs uses photogrammetric methods to capture a vast wetland environment where water and land are in constant flux. In the southeastern portion of the map, Sixmile Lake stands as a significant landmark amidst a mosaic of smaller unnamed ponds and marshy reaches. The Yetna River joins the drainage system from the south, illustrating the natural watercourses that historically served as the primary transit corridors through this part of the Alaska interior. The absence of roads or established settlements on this sheet emphasizes the wilderness character of the terrain, where river navigation and seasonal changes dictate the movement of people and wildlife.
