2016 Map of Nabesna D-4 SE

About this map

Tetlin River meanders across the northern reaches of this remote Alaskan interior landscape, carving a wide alluvial valley through the eastern Mentasta Mountains. The river's braided course and the surrounding marshy lowlands contrast sharply with the steep, unnamed ridgelines that dominate the central and southern portions of the quadrangle. In the southeast, the Kalukna River flows through high-elevation terrain, tracing a path between mountain flanks that reach toward the headwaters of the Copper River drainage. This 2016 survey, produced by the U.S. Geological Survey using imagery and elevation data from the early 21st century, documents a wilderness environment defined by significant vertical relief and the natural hydrography of these two distinct river systems.
