1955 Map of Utukok River C-5

About this map

The Kokolik River winds extensively through this Arctic terrain, its meandering course carving through a landscape dominated by thaw lakes and complex hydrological patterns. This 1955 survey captures the region during a period of significant federal oversight, as evidenced by the Naval Petroleum Reserve No 4 Boundary (Indefinite) which bisects the quadrangle. The lack of established roads or permanent settlements on the sheet underscores the remote and undeveloped nature of the North Slope in the mid-twentieth century. Instead, the geography is defined by the natural drainage of the river system and the predetermined, though unsurveyed, land lines established by the Bureau of Land Management at the Umiat Meridian.
