2017 Map of Umiat B-2 SE

About this map

The Itkillik River winds through the eastern edge of this section of the Arctic coastal plain, defining a landscape dominated by a intricate network of thaw lakes and drainage basins. This 2017 survey by the U.S. Geological Survey captures a region of the North Slope defined by its hydrological complexity and lack of permanent human infrastructure. The presence of the river serves as the primary geographical anchor for the surrounding wilderness areas delineated by the Public Land Survey System boundaries of T1s R5e, T1s R6e, T2s R5e, and T2s R6e. The terrain represents a classic example of permafrost-affected topography, where the subtle elevation changes shown by the National Elevation Dataset dictate the placement of numerous unnamed lakes and seasonal wetlands that characterize the North Slope Borough.
