2019 Map of McGrath A-4 SE

About this map

Big River dominates this interior Alaskan landscape, winding through a vast corridor of wetlands and varying elevations at the boundary of two administrative regions. This 2019 survey documents the transition between the Yukon-Koyukuk Census Area and the Bethel Census Area, a remote area defined by its natural drainage patterns rather than human settlement. The absence of roads or established towns underscores the wilderness character of the region, where the river serves as the primary geographical marker. Researchers and cartographers can examine the intricate contour lines and township grids, such as t23n r30w and t24n r29w, which provide a precise framework for this uninhabited stretch of the Alaskan interior.
