2016 Map of Ambler River B-2 SW

About this map

Ambler River winds through this expanse of the Alaska-Northwest Arctic Borough, serving as the primary geographic corridor through the mountainous terrain. This 2016 survey provides a precise look at the drainage patterns and elevation profiles of the region, captured during a period of modern topographic mapping by the U.S. Geological Survey. The map detail highlights the river's sinuous path and the complex network of surrounding ridges, defined by sharp contour intervals that illustrate the extreme verticality of the landscape. While primarily an uninhabited wilderness, the area is delineated by the Public Land Survey System grid, including boundaries for t22n r9e and t23n r9e. The map serves as a vital record of the hydrological and geological structure of this remote arctic territory, useful for researchers studying the transition of these drainage basins in the early 21st century.
