2018 Map of Black River B-5 NW

About this map

The Little Black River winds through this interior Alaskan landscape, characterized by complex oxbow lakes and vast wetland systems in the Yukon-Koyukuk Census Area. The terrain is largely dominated by the low-lying fluvial features of the river basin, with Bearnose Hill providing a distinct topographic rise in the northwestern portion of the quadrangle. Surveyed by the U.S. Geological Survey using imagery from 2009 and 2010, the map illustrates the intricate drainage patterns where the river loops back upon itself, creating a series of unnamed ponds and marshes. This map provides a clear record of the shifting river channels and hydrology of the Black River region within townships t19n r20e, t19n r21e, t18n r20e, and t18n r21e.
