2019 Map of Ophir D-1 NE

About this map

The North Fork Innoko River winds through the northern reaches of this interior Alaskan landscape, defining a broad river valley characterized by complex hydrology and seasonal wetlands. In the southern portion of the sheet, the terrain rises significantly toward the peak of Lone Jim Mtn, which serves as a prominent landmark for the surrounding wilderness. These two features illustrate the stark contrast between the low-lying alluvial plains and the uplands that separate major drainage basins. Drainage from these heights flows into Fourmile Cr, which cuts across the central townships. The absence of roads or established settlements on this 2019 survey emphasizes the continuity of the natural landscape in the Yukon-Koyukuk region, where travel is traditionally dictated by the flow of water and the contours of the mountains.
