About this map

Kohokachalla Mtn dominates the northern interior of this landscape, rising above the winding course of the Koyukuk River. The terrain is defined by the complex hydrology of the river's floodplain, where features like Curve Slough and Dog Island mark the shifting patterns of the water over time. These alluvial formations indicate a highly dynamic environment where the river frequently alters its path, leaving behind oxbows and islands that shape local navigation and land use. In the southern reaches of the map, the drainage of Slathtouka Cr carves through the lower elevations, illustrating the watershed connectivity of the Yukon-Koyukuk region. This 2016 survey provides a precise record of these landforms and water systems, which are essential for understanding the remote wilderness and traditional waterways of interior Alaska.
