1955 Map of Sagavanirktok D-5

About this map

The Kuparuk River winds through this expanse of the North Slope, revealing a landscape defined by braided waterways and thermokarst lakes as they appeared in 1955. This area, later revised in 1985, serves as a record of the terrain prior to the full development of the region's petroleum infrastructure. A single Drill Hole is noted amongst the vast network of small ponds and marshes, signifying early exploration efforts in the Arctic tundra. The geography is further marked by the Toolik River, which joins the larger Kuparuk system in the northern portion of the quadrangle. Named local landmarks such as Rubar and Nello provide specific reference points for researchers studying the historical topography and surveying of this remote Alaskan borough.
