2018 Map of Marshall D-1 NW

About this map

The Yukon River dominates this interior Alaska landscape, carving a broad, shifting course through the Kusilvak Census Area. This 2018 survey documents the complex hydrological patterns of the river valley, where the primary channel is accompanied by the expansive Poltes Slough and the winding Center Slough. These interconnected waterways and wetlands define the region's geography, dictating the movement and subsistence patterns of the area. The presence of Owl Creek in the southern portion of the quadrangle further illustrates the dense network of tributaries that feed into the Yukon system. Mapping of township and range lines like t22n r71w and t21n r71w provides a precise framework for understanding land divisions in this remote riverine environment, where the shifting waters frequently redefine the shoreline and surrounding terrain.
