The Kashunuk River meanders across this landscape in the Kusilvak Census Area, defining a vast network of wetlands and small lakes characteristic of the Yukon-Kuskokwim Delta. In the southern portion of the sheet, the terrain rises slightly at Kochilagok Hill, a rare point of elevation in an otherwise low-lying waterscape. The Nunatak River cuts through the southeastern corner, further illustrating the complex hydrography of this remote coastal plain. This 2020 representation captures the intricate drainage patterns and seasonal water bodies within the various townships, including t19n r84w and t18n r83w, offering a clear view of the region's natural geography before shifting environmental conditions further alter these waterways.
