About this map

The Selatna River and its tributary, the First Fork Selatna River, dominate this interior Alaska landscape within the Yukon-Koyukuk Census Area. The terrain is characterized by the complex meandering of these water bodies through low-lying valley floors, framed by significant topographical elevations in the eastern and western portions of the quadrangle. As captured in this 2019 data, the drainage patterns of the First Fork Selatna River reveal a dynamic hydraulic environment where the river channels shift across the basin. This USGS survey highlights the vast, uninhabited character of the region, emphasizing the natural watercourses that serve as the primary landmarks in an area otherwise defined only by the cadastral markers of the Public Land Survey System, such as t27n r34w and t28n r35w.
