About this map

The Arctic National Wildlife Refuge dominates the high-latitude terrain of this late twentieth-century survey, where the landscape is defined by the drainage patterns of the Yukon River watershed. The boundary between the Arctic refuge and the Yukon Flats National Wildlife Refuge cuts across the southern portion of the sheet, marking a transition toward the low-lying wetlands and complex water bodies of the flats. While the area is largely devoid of permanent settlements, a lone Cabin is recorded in the southern interior near a cluster of unnamed lakes. The northern reach is characterized by the headwaters of Boulder Creek, while Grayling Creek flows through the southeastern corner, illustrating the intricate hydrological network that sustains this subarctic environment.
