About this map

Dillinger River and the Jones River define the hydrography of this interior landscape in the Alaska wilderness. The terrain is characterized by the transition from high-relief alpine slopes to the braided river channels and alluvial plains typical of the Yukon-Koyukuk region. This 2019 survey documents the intricate drainage patterns where smaller tributaries descend from high elevations to meet the major river systems. The lack of named settlements or road infrastructure highlights the remote character of the territory, which remains dominated by natural topographical features rather than human development. For the geologist or wilderness historian, the contour data reveals the complex glacial and fluvial activity that has shaped the land within these township boundaries.
