2019 Map of Iditarod D-6 SE

About this map

Big Yetna River and Little Yetna River define the intricate hydrological character of this remote landscape in the Yukon-Koyukuk Census Area. The terrain is marked by the shifting meanders of these two waterways as they weave through a complex network of wetlands and low-lying alluvial plains. The map illustrates a wilderness shaped by natural drainage patterns, where the rivers are the primary landmarks in an otherwise undeveloped territory. The lack of man-made structures or transport networks highlights the isolation of this interior Alaskan region, making it a critical reference for understanding the natural geography and water flow within the Iditarod district. Researchers can observe how the larger Big Yetna River dominates the central and southern reaches while its smaller tributary branches off to the east.
