2015 Map of Teshekpuk A-4 NW

About this map

The Oumalik River winds extensively across this North Slope landscape, creating a complex network of oxbow lakes, abandoned meanders, and marshy basins. This 2015 survey by the U.S. Geological Survey illustrates a remote Arctic environment dominated by thermokarst processes, where the low-relief terrain is characterized by hundreds of unnamed thaw lakes and ponds. The river itself meanders through the eastern and southern portions of the map, carving through the Tundra within the boundaries of t10n r13w, t10n r14w, and t9n r13w. These Public Land Survey System townships provide the only formal grid for an area otherwise defined by its shifting water patterns and permafrost features. This map serves as a technical snapshot of the Arctic's hydrological systems in the early twenty-first century.
