USGS Topo · Published 1986

About this map

The Continental Divide cuts through this high-latitude terrain, marking a fundamental hydrological boundary in the central Brooks Range. This 1986 provisional survey reflects the area shortly after its formal protection under the Alaska National Interest Lands Conservation Act. The Alatna River meanders through the eastern portion of the sheet, joined by glacial tributaries including the Pingaluk River and Nahtuk River.
