2019 Map of Ruby A-4 NW

USGS Topo · Published 2019

About this map

Bonanza Creek and Lost River define the drainage patterns of this wilderness landscape in the Yukon-Koyukuk Census Area. This 2019 survey documents a region dominated by relief and watercourses rather than human infrastructure, as seen in the winding paths of Straight Creek and Wood Creek. The land is meticulously gridded for the Public Land Survey System, showing the boundaries for t14s r20e, t15s r20e, and t16s r20e as they meet the R21E ranges. These survey lines provide the primary framework for locating specific points in a territory where natural landmarks serve as the only named features. The absence of roads or established settlements emphasizes the remote nature of this Alaskan interior during the early 21st century.
