1985 Map of Lookout Ridge B-3

USGS Topo · Published 1985

About this map

The National Petroleum Reserve in Alaska dominates this 1985 survey, reflecting a landscape defined by federal land management and resource exploration in the late twentieth century. Located on the North Slope, the terrain is shaped by the winding paths of Discovery Creek and Pahron Creek, which drain a complex network of ridges and tundra. A prominent Tractor Trail cuts across the northern and central sections, providing a tangible record of the specialized transportation routes required for arctic logistical operations. The map also illustrates the foundational surveying framework of the region, clearly marking the Base Line that serves as a critical reference for the unsurveyed and unmarked land lines predetermined by the Bureau of Land Management.
