Colville River flows across the northern expanse of this North Slope terrain, defining a drainage system that includes Ipnavik River and several smaller tributaries. This 2016 survey by the U.S. Geological Survey documents the braided watercourse patterns and topographic contouring of a remote landscape within the Howard Pass D-2 SE quadrangle. The map tracks the winding path of Blankenship Cr and Culo Cr through the southern sections, illustrating the complex hydrography of the Alaskan Arctic. Geologic and environmental researchers can observe the distinct elevation changes and alluvial features that characterize this sub-arctic environment, providing a technical baseline for studying northern watershed dynamics.
