Ivishak River meanders across this northern landscape within the t4s r18e and t5s r18e land divisions. This 2017 survey by the U.S. Geological Survey documents a remote reach of the North Slope, where the terrain is defined by the broad river valley and the rising elevations of the surrounding Brooks Range foothills. The map provides a detailed view of the braiding water channels and the precise township and range boundaries, including t4s r19e and t5s r19e, which are essential for locating specific land parcels in this vast unpopulated wilderness.
