2015 Map of Ophir C-4 SW

About this map

The Innoko River winds through this interior landscape, exhibiting a dense network of abandoned meander loops and oxbow lakes that define the fluvial history of the region. This 2015 topographic study by the U.S. Geological Survey details a remote portion of the Yukon-Koyukuk area where the water-saturated terrain is shaped by the river's shifting course. In the southern reach of the quadrangle, Hammer Cr feeds into a complex system of ponds and marshes. The map is primarily organized by the Public Land Survey System, showing several townships including t22s r5e and t21s r5e. The lack of named settlements or roads reflects the wilderness character of this Alaskan interior, making it a valuable reference for understanding the natural drainage patterns and land divisions in one of the state's most secluded corridors.
