1954 Map of Ophir D-3

About this map

The Tlatlils Hills dominate this mid-century landscape in interior Alaska, rising above an intricate network of wetlands and waterways. Surveyed using photogrammetric methods from aerial photographs taken in 1953 and 1955, the map captures the untouched hydrological patterns of the Mud River as it meanders through the northern section of the quadrangle. The southern reaches are defined by the courses of Galatea Creek and Wapoo Creek, which thread through the low-lying terrain between the prominent ridges. This 1954 field-annotated survey is notable for its absence of man-made structures, trails, or settlements, providing a clear record of the natural topography and drainage basins of the Yukon-Koyukuk region before any modern infrastructure development.
