About this map

The Colville River Delta dominates this mid-century topographic study, where the expansive river system meets the waters of Harrison Bay. The landscape is defined by an intricate network of braided channels, including the Kupigruak Channel, and thousands of thaw lakes that pockmark the tundra. Landforms such as Anachlik Island and Nuekshat Island emerge within the Colville River, while names like Norma, Orion, and Nimrod identify specific locations across the flat, water-logged terrain.

Farther inland, the hydrology becomes even more complex as the Miluveach River and Kalubik Creek meander toward the coast. A notable topographical feature is Pikonik Mound, a distinct pingo or rise in an otherwise low-lying Arctic environment. This 1955 survey, compiled from aerial photographs, illustrates the untouched state of the North Slope before significant industrial infrastructure altered the region, focusing instead on the natural course of the Kachemach River and the seasonal patterns of the delta.
