Kobuk Valley National Park encompasses a significant portion of this landscape within the Northwest Arctic Borough. The terrain is defined by the prominent Jade Mountains in the northeast, where steep elevation changes are documented by dense contour lines. This Arctic environment is drained by the meandering Jade Cr, which flows through several townships including t21n r3e and t20n r3e. The map illustrates a largely roadless wilderness area, reflecting the remote nature of this portion of Alaska as it was managed in the early 21st century. Researchers can trace the complex hydrography and topography that characterize the region's protected parklands and distinctive mountain ranges.
