Twentynine Mile Ridge dominates the southeastern quadrant of this Alaska interior landscape, providing a topographical anchor in the Yukon-Koyukuk Census Area. The terrain is defined by the drainage patterns of Fortymile Cr, which winds through the central and northern sections of the map. In the southwest corner, Howard Lake sits as the primary body of standing water, highlighting a localized wetland environment. This 2017 survey reflects the remote and largely undeveloped character of the territory, organized by the township and range lines of t22n r1w, t22n r1e, t21n r1w, and t21n r1e. The relative lack of industrial or residential labels underscores the wilderness state of this subarctic region in the early twenty-first century.
