2015 Map of Ophir C-5 SE

About this map

Innoko River dominates this interior landscape, winding in a complex series of tight oxbow loops and meanders through the lowlands. The river's serpentine path is characteristic of the dynamic hydrology in the Yukon-Koyukuk region, creating a network of sloughs and abandoned channels. Tributaries like Magitchlie Cr and Hammer Cr feed into this system, which defines the drainage patterns of the surrounding wilderness. The terrain is marked by a clear transition from the wet, low-lying river valley to the rising elevations found in the southwestern corner of the sheet. This 2015 survey, published by the U.S. Geological Survey in cooperation with the Alaska Dept. of Transportation, provides a precise look at the shifting waterways and topographical contours of the Alaskan interior.
