About this map

Yukon Flats dominates the landscape in this interior Alaskan wilderness, as seen through photography from 1978 and 1981. The map depicts a complex hydrological network within the Yukon Flats National Wildlife Refuge, where numerous unnamed water bodies are identified only by their surface elevations, such as Wl 982t in the north and Wl 529t in the south. The terrain is characterized by meandering watercourses and expansive wetlands, typical of this subarctic basin. This 1990 provisional sheet highlights the intricate drainage patterns of the region, featuring specific points like Wl 696t and Wl 708t that illustrate the minimal vertical relief across the flats. The survey serves as a fundamental record of this remote ecosystem before further modern changes, focused entirely on the natural features and topographic elevations of the wilderness.
