2019 Map of Iditarod C-4 SE

About this map

The Kuskokwim Mountains dominate the interior landscape of this region, shaping the complex drainage patterns of the western Alaskan wilderness. The map documents a rugged watershed where the Dishna River flows along the eastern margin, fed by a network of tributaries including Otter Cr and its distinct branches. The divergence of the N Fork Otter Cr and the S Fork Otter Cr across the central terrain illustrates the geographical isolation of the Yukon-Koyukuk Census Area. This survey provides an essential look at the drainage systems of the Alder Cr basin before further environmental shifts or topographic changes. The absence of roads or permanent structures reflects the primitive state of the land, preserving the natural hydrological and geological features of the subarctic interior.
