2019 Map of McGrath D-1 SW

About this map

Big Salmon Fork defines the southwestern corner of this interior Alaskan landscape, winding through a region marked by extensive wetland systems and subtle elevation changes. The hydrology is dominated by Deepbank Cr, which meanders across the central and eastern sections of the quadrangle, joined by smaller tributaries like No Cr. This 2019 survey by the U.S. Geological Survey illustrates a wilderness largely defined by its natural drainage patterns rather than human infrastructure, as no roads, settlements, or structures are noted within the township boundaries of T31N and T32N. The map provides a clear record of the Kuskokwim River watershed's upper reaches, where the complex lattice of seasonal streams and ponds shapes the movement of the terrain.
