About this map

The Yukon River dominates the western and northern reaches of this landscape, its expansive braided channels and shifting sediment creating a complex network of waterways. Centrally located within these waters is Jokinaugh Island, a large landmass surrounded by the river's main flow and secondary channels. To the west, Long Point juts into the current, serving as a distinct landmark along the riverbank.

South of the river, the terrain transitions into a mosaic of wetlands and smaller drainage systems. Alfred Creek and Rogers Cr meander through the low-lying interior, their paths defining the hydrology of the interior flats. The southeastern portion of the map shows a rise in elevation, where contour lines indicate more defined hills, contrasting with the river-fed plains to the north. This 2017 survey by the U.S. Geological Survey captures a wild stretch of the Yukon-Koyukuk region where the river remains the primary architect of the environment.
