About this map

The Noatak River meanders across the northern portion of this landscape, its braided channels and gravel bars defining the drainage patterns of the western Arctic. As part of the Noatak National Preserve, the area remains one of the largest undisturbed watersheds in North America. The map captures the confluence where the Aniuk River joins the main river from the north, a significant geographic landmark for navigation in the region's interior.

Contour lines reveal the surrounding elevation, showing the transition from the broad river valley to the rising upland terrain. While the terrain is devoid of permanent settlements, the land is partitioned by the Public Land Survey System, including sections within t30n r4e and t29n r5e. This survey provides a baseline of the Arctic wilderness prior to the modern impacts of climate and hydrology on the river's shifting path.
