About this map

The Nabesna River winds through a vast expanse of wetlands and alluvial flats within the northern reaches of the Tetlin National Wildlife Refuge. This landscape is defined by the shifting course of the main channel and the branching Nabesna Slough, illustrating a dynamic riparian environment where water levels dictate the character of the terrain. The northern half of the sheet is dominated by these marshy lowlands, which serve as a critical habitat within the larger refuge system.

To the south, the topography transitions abruptly as the marsh gives way to the rising elevations of the Black Hills. This sudden change in relief is marked by the convergence of several smaller waterways, including the Cheslina River and Kalutna River, which drain the uplands into the Nabesna valley. The map provides a clear look at the intersection of these distinct ecological zones in a region of Alaska largely shaped by natural processes rather than human settlement.
