Continental Divide winds through this remote northern landscape, marking the high separation of drainage basins in the central Brooks Range. This section of Gates of the Arctic National Park is characterized by its high-elevation terrain and lack of human infrastructure, where the primary drainage is found along Portage Cr. The boundary between the Northwest Arctic Borough and the Yukon-Koyukuk Census Area follows the high ridgelines of the divide, emphasizing how the natural geography of the region defines its administrative limits.
