About this map

The Kobuk River Delta dominates the eastern expanse of this 1951 aerial study, revealing a intricate network of waterways where the river meets the sea. This landscape is defined by the braided paths of the Riley Channel, Lewis Rich Channel, and Rolikatuk Channel, which snake through a mosaic of wetlands and tundra ponds. To the west, the narrow Baldwin Peninsula acts as a natural barrier, separating the sheltered waters of Hotham Inlet from the open Kotzebue Sound.

The mapping, based on photogrammetric methods from 1951 with minor revisions in 1974, captures the coastal morphology before significant modern shifts. Researchers can trace the specific hydrography of the southern delta reaches, including the Emanvicrok Channel, providing a precise record of the shoreline and drainage patterns as they existed in the mid-20th century. The land lines shown here represent unsurveyed and unmarked locations predetermined by the Bureau of Land Management, reflecting the remote nature of this Arctic maritime environment.
