The Kukpowruk River meanders across this expanse of the De Long Mountains, forming a complex drainage system in the North Slope's arctic tundra. This 2014 survey documents the hydrographic character of the region, where the Sooner River joins the larger drainage network. The map reveals a landscape defined by dramatic elevation changes, with landforms rising significantly away from the river valleys. The absence of roads, settlements, or structures underscores the area's isolation within the North Slope Borough, where the natural terrain and watercourses remain the primary features of the land. This detailed topographical record serves as a primary source for understanding the physical geography and hydrology of this specific corridor in the De Long Mountains.
