The Innoko River winds through the southern portion of this interior landscape, defining the primary drainage for this remote section of the Yukon-Koyukuk region. In this modern 2014 survey, the terrain is characterized by expansive wetlands and low-lying river valleys, with the hydrology data sourced from the National Hydrography Dataset. The survey is organized by the Public Land Survey System, showing sections within townships t24s r1e, t25s r1e, and t26s r1e, along with their eastern counterparts in Range 2E. While the map is devoid of named settlements or man-made landmarks, the detailed contour lines and river path provide essential data for understanding the historical floodplains and natural boundaries of this Alaskan wilderness.
