2019 Map of McGrath A-4 NE

USGS Topo · Published 2019

About this map

Big River meanders through the heart of this interior Alaskan landscape, shaping a complex network of wetlands and shifting channels. Surveyed in 2019, the terrain is defined by the expansive alluvial reaches of the river as it winds between the township boundaries of t25n r30w, t25n r29w, and t24n r29w. The map documents a sparsely settled wilderness where the natural hydrology of the Big River valley remains the primary geographic feature, providing a clear record of the river's path and the surrounding marshlands within the Yukon-Koyukuk Census Area.
