2019 Map of Ruby A-4 NE
USGS Topo · Published 2019About this map
Lost River meanders across this interior landscape within the Yukon-Koyukuk Census Area, defining the drainage patterns of a region shaped by high-latitude hydrology. The terrain is structured by the Public Land Survey System, specifically within the townships of t14s r21e, t15s r21e, and t16s r21e, reflecting the systematic grid applied to the Alaskan wilderness. In the northwest corner, Bonanza Cr cuts through the elevations, its name suggesting the prospecting history common to this part of the Alaska interior. This 2019 data release from the U.S. Geological Survey utilizes high-resolution elevation datasets and imagery to record the precise contours of the valleys and ridgelines that separate these watercourses.
