2019 Map of Ruby A-3 SE

USGS Topo · Published 2019

About this map

The Nowitna River meanders across this interior landscape within the Yukon-Koyukuk region, illustrating a classic pattern of northern fluvial geomorphology. This 2019 survey documents a wilderness environment defined by shifting watercourses and complex oxbow formations, particularly where the Sulukna River enters from the southeast. The lack of named settlements or road infrastructure highlights the persistent isolation of the Ruby A-3 SE quadrangle, where the land is primarily partitioned by the Public Land Survey System as seen in townships t16s r24e and t17s r25e. This data serves as a modern baseline for understanding the hydrologic character of the subarctic river systems in central Alaska.
