2016 Map of Hughes A-4 NW

USGS Topo · Published 2016

About this map

The Hogatza River winds through the northwestern reaches of this interior Alaskan landscape, while the Koskalantha Cr cuts across the northeastern corner. This 2016 survey documents a vast area of the Yukon-Koyukuk region defined by its complex drainage patterns and shifting elevations. The terrain is marked by a series of high ridges and deep valleys, reflected in the intricate contour lines that dominate the sheet. Aside from these primary waterways, the map is characterized by its isolation, showing a wilderness area organized by the Public Land Survey System township and range lines, including t10n r18e and t9n r19e. The absence of roads or permanent settlements in this quadrangle highlights the remote character of the Koyukuk River basin.
