1899 Map of Fortymile

About this map

Eagle and a network of remote post offices anchor this late 19th-century survey of the Yukon-Tanana region along the international boundary. Surveyed just after the height of the Klondike Gold Rush, the map traces the vital waterways of the Fortymile River and its numerous tributaries, including Mosquito Fork and Walker Fork. The infrastructure of the era is evident in the Winter Trail and the U.S. Telegraph Line (Abandoned), which provided essential, if fleeting, connectivity through the high-elevation terrain near Glacier Mountain and Fortymile Dome. Several established post offices such as Steel Creek P.O., Franklin P.O., Jack Wade P.O., and Chicken P.O. highlight the early mining settlements and supply points that defined the local economy during this territorial period. The rugged topography is defined by the massive drainage systems flowing toward the Yukon River, serving as the primary corridors for transport and exploration before the development of modern roads.
