2017 Map of Kantishna River D-4 SE

About this map

Chitanatala Mountains define the southern landscape of this remote Yukon-Koyukuk interior, providing a dramatic vertical contrast to the winding path of the Cosna River. The river traverses the eastern sections of the quadrangle, carving a serpentine route through the lowlands as it flows northward. This 2017 edition illustrates the complex hydrography of the Alaskan interior, showing how the drainage patterns are strictly governed by the proximity of the mountains. Beyond the primary waterway, the terrain is marked by a network of smaller drainages and shifting elevations across the township and range boundaries of t1n r20w, t1s r21w, and t2s r20w. This specific survey offers a detailed view of an area shaped by glacial and fluvial processes, where the presence of the Cosna River indicates a dynamic landscape of seasonally changing water levels and wilderness navigation.
