2016 Map of Ambler River A-3 NE

About this map

The Ambler River winds through this section of the Northwest Arctic borough, creating a complex network of braids and gravel bars across the low-lying terrain. The hydrography of the region is characterized by significant seasonal shifts, as seen in the wandering course of the river and its confluence with Naniratkohort Cr. To the north, the elevation rises sharply into a series of ridges, contrasting with the expansive wetlands and small bodies of water like Lake Anirak found in the southern reaches. This 2016 survey, produced with data from the Alaska Dept. of Transportation and other agencies, provides a clear view of the Public Land Survey System boundaries, including t21n r8e and t20n r8e, which define the administrative layout of this remote wilderness. The northern portion of the map is dominated by the drainage basin of Katurivik Cr, where the terrain begins its ascent away from the river valley.
