2015 Map of Ophir C-4 NW
USGS Topo · Published 2015About this map
Innoko River meanders through the southeastern portion of this landscape, carving deep oxbow loops across the terrain. This interior region of Alaska, documented by the U.S. Geological Survey in 2015, is characterized by its complex hydrography and shifting river channels. In the northeastern corner, the Mud River flows into the quadrangle, highlighting the water-dependent geography that historically governed transport and survival in the Yukon-Koyukuk region. The absence of road infrastructure or named settlements on this sheet reflects the remote nature of the territory, where the river systems remain the primary geographic anchors for navigation and land use.
