About this map

Ruby serves as the focal point of this interior Alaskan landscape along the south bank of the Yukon River. The 1950s terrain is characterized by a massive network of braided waterways and sloughs, including Big Island Slough and Kokrines Slough, which weave around islands like Ham Island and Edith Island. To the south, the Nowitna River meanders through expansive lowlands before reaching the higher elevations of the Monzonite Hills and Kokrines Hills.

Resource extraction and early infrastructure are evident throughout the quadrangle, with a Telegraph Line providing a vital communication link across the wilderness. Mining activity is concentrated in the southern reaches near settlements such as Poorman and Placerville, where a Placer Mine and Greenstone Mine are located. Remote outposts like Sulatna Crossing and various scattered Cabins highlight the isolated nature of settlement in this era, while prominent landmarks like Ruby Mountain and Boston Dome provide navigational anchors for the surrounding territory.
