2017 Map of Harrison Bay B-2 NE

About this map

Harrison Bay dominates the northern reaches of this coastal Alaskan landscape, where the Colville River delta fragments into a complex network of arctic waterways. The map illustrates a highly dynamic environment defined by braided watercourses and migratory channels, including the prominent Elaktoveach Channel and the southern Kupigruak Channel. A single point of modern infrastructure, the CD-3 Airstrip, stands out against the vast expanse of wetlands and small tundra ponds that characterize the North Slope. This 2017 survey by the U.S. Geological Survey provides a detailed record of the shifting shoreline and the intricate drainage patterns of the Tumayauak Channel during a period of ongoing geographical change in the region.
