1956 Map of Charley River D-4

About this map

Yukon Flats characterizes this interior Alaskan landscape, a vast area of wetlands and low-lying terrain within what was designated as a National Wildlife Refuge. The map, based on aerial photography from the mid-1950s, reveals a complex network of marshes and unnamed water bodies that define the region's drainage patterns. Elevation rises toward the northeast where Bear Mountain stands as a prominent topographical landmark. Flowing from these higher elevations, Bear Mountain Creek traverses the northern portion of the quadrangle. This survey serves as a primary record of the untouched wilderness in the Charley River area before more modern environmental classifications were formalized, illustrating a landscape defined almost entirely by its natural hydrology and relief rather than human infrastructure.
