About this map

The Nulato Hills dominate this interior Alaskan landscape, where the terrain is defined by the winding course of the Yellow River. In this 2015 U.S. Geological Survey representation, the complex drainage patterns of the region are clearly visible as the river moves through the valleys between the northern highlands and the southern Blackburn Hills. Small waterways like Thompson Cr and Simon Cr feed into the larger river system, illustrating the hydrology of this roadless wilderness.

This area, located within the Yukon-Koyukuk region, remains a significant example of an undisturbed subarctic environment. The lack of human infrastructure on the map—no roads, buildings, or landing strips are noted—emphasizes the isolation of the territory and the importance of natural landmarks for navigation. Researchers and cartographic enthusiasts can use this survey to study the precise topographic contours and the natural shifts in the river corridors of Western Alaska.
