2016 Map of Ambler River C-3 SE

About this map

Noatak National Preserve encompasses a significant portion of this Arctic landscape, where the northern wilderness remains shaped by its ancient drainage systems. The survey detail focuses on the upper reaches of the Redstone River, which meanders across the southern half of the sheet, and its tributary, the Imelyak River, flowing from the north. This area of the Northwest Arctic Borough is defined by these isolated river corridors, which have long served as vital navigational landmarks in a region devoid of permanent road infrastructure or settlements. The topographic data reveals a complex network of high ridges and narrow valleys, illustrating the transition from the high Brooks Range foothills toward the lower river basins. This map serves as a primary record of the hydrological patterns and land management boundaries within one of the most protected and least altered ecosystems in Alaska.
