2016 Map of Umiat A-5 NW

About this map

The braided channels of the Colville River dominate the northern landscape of this North Slope region, illustrating the dynamic hydrology of the Alaskan Arctic. In this 2016 survey, the river system creates a complex network of gravel bars and shifting waterways as it moves through the expansive river valley. To the south, the terrain rises steadily toward the foothills, where Ninuluk Creek cuts through the uplands before joining the main river valley. The map provides a detailed view of the Public Land Survey System grid, showing the intersections of townships and ranges such as t2s r4w and t3s r4w. This specific geography highlights the transition from the broad, active alluvial plain to the higher, dissected ridges of the inland tundra, offering a clear picture of the natural drainage patterns in a remote part of the borough.
