2019 Map of Ruby A-1 SE

USGS Topo · Published 2019

About this map

Sethkokna River defines the northwestern reaches of this interior landscape, marking a winding watercourse through the vast public lands of the Yukon-Koyukuk Census Area. The terrain is shaped by the drainage systems of the river and the smaller Sischu Cr in the southeast, reflecting the untouched wilderness of central Alaska. Surveyed primarily to document the Public Land Survey System, the map detail focuses on the township and range grids, including t16s r28e and t17s r30e. This 2019 data provides a clear record of the hydrography and elevation contours in a region where human settlement is sparse and the natural geography of the river basins remains the primary feature.
