About this map

The Arctic National Wildlife Refuge dominates this section of the North Slope, revealing a landscape defined by the shifting braids of Arctic waterways. The Niguanak River flows through the western portion of the quadrangle, while the Sikrelurak River and Angun River traverse the central and eastern sections, respectively. These rivers navigate a vast expanse of wetlands, where the intricate drainage patterns suggest a complex hydrology characteristic of the coastal plain. The absence of roads or permanent structures underscores the remote and protected nature of this environment, preserving a snapshot of the region's natural state as it was documented in the early twenty-first century.
