1954 Map of Ophir A-5

About this map

Iditarod River meanders across this interior landscape, defining a complex hydrologic network in the years following mid-century aerial photography. This survey, compiled from 1953 and 1954 photographs, reveals a wilderness dominated by expansive wetlands and shifting watercourses rather than permanent human settlements. The Yetna River flows through the lower half of the quadrangle, eventually meeting larger drainage systems in a region characterized by low relief and high water saturation. A significant landmark in this watery expanse is Sixmile Lake, which provides one of the few large open-water reference points in an area otherwise filled with smaller unnamed ponds. This map captures the region before extensive modern development, showing land lines predetermined by the Bureau of Land Management according to the Kateel River Meridian.
