2015 Map of Ambler River A-4 NE

About this map

Ambler River and the Redstone River converge in this northern landscape, creating a complex network of meanders and oxbow lakes typical of the Arctic river systems in the Northwest Arctic region. The terrain is defined by the transition from low-lying riparian wetlands to the rising elevations of the Manullyisat Hills in the southwest corner of the sheet. Surveyed under the Public Land Survey System, the map detail includes the boundaries of t21n r5e, t21n r6e, t20n r5e, and t20n r6e. Smaller waterways like Agnes Cr drain the higher ground to the north, feeding into the larger river valleys that dominate the local topography. This 2015 USGS record provides a precise look at the hydrology of the area before environmental shifts significantly alter these remote western Alaskan drainages.
