Greenstone Ridge dominates the central portion of this 2017 survey, serving as a significant topographical divide within the Bethel Census Area. The landscape is defined by its dramatic elevation changes and a series of high ridges that channel several significant waterways. Along the eastern edge, the Kisaralik River and its tributary, Swift Cr, cut through the terrain, while the Kasigluk River winds through the southwestern corner. The mapping of these river systems and the accompanying contour data provides an essential record of the hydraulic patterns in this part of the Alaska interior. The absence of roads or established settlements emphasizes the remote, water-centric nature of the region, where the terrain itself dictates the lines of travel and drainage.
