2020 Map of Ikpikpuk River A-4 SE

About this map

The Colville River carves a massive, winding path through this North Slope landscape, creating a complex network of sandbars and braided channels as it flows eastward. This hydrographic pattern suggests a highly dynamic river system, subject to the intense seasonal fluctuations characteristic of the Arctic. Joining from the south, the Kurupa River meanders across the flat, marshy lowlands before its confluence with the Colville. The lack of named settlements or man-made infrastructure emphasizes the isolation of this region, defined primarily by its watercourses and the Public Land Survey System boundaries, including t4s r13w and t5s r12w. The topographical detail provided by the U.S. Geological Survey focuses on the subtle elevation changes of the river bluffs and the surrounding tundra, providing an essential record of the natural hydrology in this remote northern territory.
