1952 Map of Ruby C-4

About this map

The Nowitna River meanders through this interior Alaska landscape, creating a complex network of oxbow lakes and abandoned channels that define the eastern edge of the quadrangle. Photogrammetric methods from 1952 capture a vast expanse of wetlands and low-relief terrain, where drainage patterns are dictated by subtle shifts in elevation. The Sulatna River joins the southern drainage system, while Big Creek and Monzonite Creek flow through areas of dense marshland. This survey reflects the region's character before modern infrastructure reached deep into the Yukon-Koyukuk area, showing land lines predetermined by the Bureau of Land Management under the Kateel River Meridian. The absence of roads or trails highlights the reliance on waterways like Smith Slough for navigation through this wilderness during the mid-twentieth century.
