1952 Map of Ruby

About this map

The Yukon River serves as the central artery for this remote region of central Alaska during the mid-twentieth century. Near the settlement of Ruby, the river bifurcates around Big Ruby Slough, while a Telegraph Line and a series of trails connect riverside outposts to the interior. Moving south from the main channel, the landscape transitions into the high elevations of the Kokrines Hills and Boston Dome. This period of survey reveals the remnants of interior gold-mining activity, with small settlements like Placerville, Poorman, and Ophir dotting the drainages of the Sulatna River. The presence of several Placer Mines and a Landing Area indicates the persistent reliance on both river and air transport for resource extraction. Notable navigational and land features such as Sulatna Crossing and Tamarack Bluff provided critical landmarks for those traversing the extensive river networks of the Nowitna River and its tributaries.
