1964 Map of Umiat

About this map

The Colville River and its major tributaries dominate this North Slope terrain, recorded during a period of strategic exploration within the Naval Petroleum Reserve No 4. The landscape is defined by its massive river systems, including the Anaktuvuk River, Nanushuk River, and Itkillik River, which wind through a series of prominent bluffs and hills like Sentinel Hill and Umiat Mountain. Evidence of mid-century industrial activity is anchored by the Gubik Gas Field, while a long Tractor Trail cuts across the tundra north of the Killik River. This survey provides a look at the region’s topography before the development of the Dalton Highway, highlighting the remote bluffs such as Shale Wall Bluff and the numerous small lakes like Shirukak Lake and Dogbone Lake that dot the river valleys.
