2019 Map of McGrath A-4 NW

USGS Topo · Published 2019

About this map

Big River carves through the northeastern corner of this interior Alaskan landscape, serving as the primary drainage for a region dominated by high-elevation contours. The map captures the remote expanse of the Yukon-Koyukuk Census Area within the legal frameworks of t25n r31w and t25n r30w, illustrating a terrain defined entirely by its natural hydrology and topographic relief. With no roads or permanent structures indicated, the survey emphasizes the undisturbed nature of the wilderness as it was documented in the early twenty-first century, providing a baseline for environmental study and geological exploration.
