2015 Map of Ambler River A-4 NW

About this map

Jade Mountains dominate the central landscape of this Northwest Arctic quadrangle, where steep elevation contours reveal the dramatic rise of these peaks above the surrounding river valleys. The hydrography of the region is defined by the Ambler River, which winds through the southeastern corner of the sheet, and the extensive drainage system of Miluet Cr branching across the eastern half. In the southern reaches, Kopshesut Cr flows through lower elevations, illustrating the transition from the high ridges of the mountains to the river basins below. This 2015 survey by the U.S. Geological Survey details the rugged topography of a remote interior Alaska wilderness, emphasizing the natural drainage patterns and mountain terrain that dictate the geography of the Kobuk River valley region.
