2019 Map of Medfra D-5 SW

About this map

The S Fork Sulukna River and Susulatna River carve through the interior wilderness of the Yukon-Koyukuk region, defining the complex drainage patterns of this Alaskan landscape. This 2019 survey captures the area in its modern state, showing a topography dominated by ridgelines and creek beds such as Oar Cr. The absence of roads or permanent settlements within the quadrangle highlights the isolation of this terrain, where the hydrography provides the only navigable corridors. Modern surveying techniques from the 2010s are utilized here to document the shifting courses of these interior waterways and the precise contours of the surrounding uplands.
