1956 Map of Demarcation Point B-3

USGS Topo · Published 1966

About this map

Arctic National Wildlife Range defines the landscape in this 1956 topographical study of the Alaskan North Slope. This remote territory, mapped just as the Arctic National Wildlife Range was being established by the U.S. Geological Survey and the Bureau of Land Management, captures a wilderness of steep contours and high-altitude drainage systems. The Egaksrak River and Ekaluakat River carve deep valleys through the terrain, illustrating the hydrologic patterns of the Brooks Range foothills before modern development. Because the map was created using photogrammetric methods from 1956 aerial photographs, it provides a precise record of the landforms and the established Base Line in a region that remained largely unsurveyed and unmarked on the ground at the time of publication.
