1954 Map of Melozitna D-6

About this map

The Koyukuk River winds through a dense network of waterways in this mid-century Alaskan interior landscape. The region is defined by its complex hydrologic patterns, where the main channel bypasses massive landforms like Treat Island and feeds into a series of bypasses including Cutoff Slough and Messy Slough. To the south, the terrain opens into the Dulbi Flats, a saturated lowland where the Nogoyalna Slough meanders toward the prominent Nododehon Lake. Based on 1952 aerial photography, the map reveals an environment of constant flux, with oxbows and intricate drainage systems that illustrate the shifting nature of the arctic floodplain. Apart from the geographical marker at Winthrop Point, the area remains largely devoid of permanent human infrastructure, reflecting the wilderness character of the Yukon-Koyukuk region during the 1950s.
