2019 Map of Iditarod D-4 SW

About this map

The Iditarod River meanders through this landscape within the Yukon-Koyukuk Census Area, defining a low-lying basin characterized by complex hydrology. Numerous small tributaries, including First Chance Cr and Twin Island Cr, drain into the main river channel from the surrounding hills. This 2019 survey documents the intricate network of wetlands and ponds that dominate the central sections of the quadrangle. The terrain transitions from these water-logged lowlands to higher elevations in the east and west, where labels like Glacier Cr and Moose Cr indicate the start of the watershed's feeder streams. The lack of named roads or settlements underscores the wilderness character of this region, reflecting a landscape primarily shaped by natural drainage patterns rather than human infrastructure.
