2016 Map of Ophir A-5 SE

USGS Topo · Published 2016

About this map

Sixmile Lake dominates the central landscape of this western Alaska interior region, situated within the expansive drainages of the Big Yetna River. The river follows a highly sinuous path through the western portion of the terrain, its tight meanders and oxbow formations indicating a landscape shaped by persistent hydraulic action across a low-gradient floodplain. This 2016 survey by the U.S. Geological Survey details the intricate hydrography of the Yukon-Koyukuk region, where the vast network of unnamed ponds and wetlands surrounding the primary water bodies reflects the complex drainage patterns of the Alaskan bush. The map serves as a primary record of the natural topography and waterway orientations prior to more recent environmental shifts.
