About this map

Colville River meanders across the southern reaches of this landscape in the North Slope Borough, carving through a vast network of drainage basins. This 2016 survey emphasizes the complex hydrography of the Alaskan arctic, where the river's path is defined by numerous smaller ponds and wetlands. The topographic contours reveal the subtle elevation shifts in a region largely defined by the Public Land Survey System grids of T5S R21W, T5S R20W, T6S R21W, and T6S R20W. This map records the late-twentieth and early twenty-first-century state of the terrain as documented by the National Elevation Dataset and the Colville River corridor’s natural hydrology.
