1985 Map of Lookout Ridge B-4

About this map

The National Petroleum Reserve in Alaska dominates this 1985 survey, providing a detailed look at the North Slope's remote interior hydrology and surveying markers. The landscape is defined by the winding course of the Kaksu River in the northwest and Liti Creek further south. This map captures a specific moment in the management of these public lands, showing the intersection of natural drainage systems with the rigid administrative grid of the Base Line and various township boundaries. Scattered across this vast expanse are isolated points of interest such as John, Let, and Dam, which likely served as remote monitoring or survey markers. A lonely Tractor Trail provides the only evidence of overland transportation, reflecting the logistical challenges of surveying and exploring this region before modern infrastructure was established.
