1956 Map of Beaver B-5

About this map

Long Ridge defines the northern reaches of this interior landscape, where the terrain drops sharply into a complex network of wetlands and tundra lakes. Surveyed in the mid-1950s using photogrammetric methods from aerial photographs, the map reveals a wilderness shaped by water. Large bodies such as Tishdogatumina Lake, Echoing Lake, and Savayeit Lake dominate the southern half of the sheet, illustrating the low-relief drainage patterns characteristic of the Yukon-Koyukuk region. The West Fork of The Forks meanders through the eastern section, providing a primary drainage route through the saturated lowlands. This survey captures the natural state of the Alaskan interior before modern development, offering a precise view of the hydrology and topography as it appeared during the territorial era.
