2016 Map of Tanana C-4 SW

About this map

Tozitna River meanders across the central portion of this interior landscape, marking a prominent hydrological feature in a region defined by its drainages. The river's winding path through the valley floor is joined by smaller tributaries like Crooked Cr, illustrating the complex water network that historically served as primary transportation corridors before the development of modern infrastructure. This 2016 survey by the U.S. Geological Survey documents the topography and natural boundaries of the Yukon-Koyukuk region, capturing the remote terrain in high detail. The lack of named settlements or road infrastructure emphasizes the wilderness character of the area, providing a clear baseline for researchers studying environmental changes or indigenous land use patterns within the vast Alaska interior.
