2017 Map of Chandalar D-4 SW

About this map

The North Fork Chandalar River cuts an east-west path through this interior Alaska landscape, providing the primary geographic corridor within an otherwise high-elevation wilderness. This 2017 survey by the U.S. Geological Survey documents the drainage patterns and relief across a series of townships, including t35n r6w, t35n r5w, t34n r6w, and t34n r5w. The lack of named human settlements or road infrastructure emphasizes the undeveloped character of the Yukon-Koyukuk Census Area in the early 21st century. Instead, the map is defined by its extreme topography, where steep ridges fall away to the river valley, serving as a baseline for environmental studies and backcountry navigation in the Brooks Range foothills.
