About this map

Ruby serves as the focal point for this interior Alaskan landscape, situated along the southern bank of the Yukon River where the waterway winds past Big Ruby Island Slough. This 1952 survey, with revisions into the mid-1960s, documents a region defined by its waterway-driven economy and isolated mining settlements. Small outposts and camps like Long, Placerville, and Ophir are connected by trails and rivers rather than a developed road network, reflecting the self-contained nature of mid-century frontier life.

Relief shading emphasizes the prominent terrain of the Kokrines Hills to the north and the Monzonite Hills centrally, while the winding course of the Nowitna River dominates the eastern lowlands. Researchers will find numerous remote landmarks including Sulatna Crossing and Monument Rocks, alongside evidence of resource extraction at the Placer Mine. The map captures the intricate drainage patterns of the Sulatna River and Sischu Creek, illustrating the complex geography that governed movement and prospecting in the Yukon-Koyukuk region.
