2017 Map of Ophir A-6 SW

USGS Topo · Published 2017

About this map

The Innoko River winds through this interior Alaskan wilderness, defining a landscape of complex wetlands and meandering waterways within the Innoko National Wildlife Refuge. This 2017 survey captures the intricate river systems where the Iditarod River and Netletna River intersect with the broader Innoko basin. The terrain is characterized by oxbow lakes and shifting fluvial patterns, illustrating the dynamic nature of the Yukon-Koyukuk region. Mapping of these remote corridors provides critical spatial data for understanding the hydrology of the Innoko flats, an area dominated by seasonal water movement and a lack of permanent human settlements or road infrastructure.
