1956 Map of Charley River D-3

About this map

Bear Mountain and the neighboring Fanny Mtn anchor the northern reaches of this mid-century survey within the Yukon-Koyukuk region. The landscape is defined by its intricate drainage patterns, where the winding Wood River meanders along the eastern boundary and Van Hatten Creek flows through the southern terrain. This 1956 field-annotated sheet reflects a period when topographic data was largely derived from aerial photogrammetric methods, capturing an unsurveyed wilderness where land lines were predetermined by the Bureau of Land Management rather than physically marked on the ground.
