About this map

Tonzona River dominates this interior landscape as it winds through the Yukon-Koyukuk region, illustrating a remote corridor defined by active glacial-fed waterways. The drainage patterns of the North Fork Jones Creek reveal a complex network of seasonal channels and alluvial plains typical of this subarctic environment. To the southeast, the rising elevations of the Birch Hills provide a distinct topographic contrast to the surrounding river flats. This area, largely defined by its township and range boundaries such as t28s r28e and t28s r29e, represents a significant stretch of wilderness where the natural hydrography serves as the primary landmark for navigation and land management.
