1956 Map of Demarcation Point B-3

About this map

The Egaksrak River and Ekaluakat River dominate this 1956 landscape, showcasing the complex braided drainage patterns characteristic of the North Slope. Flowing from the southern highlands, these waterways carve through a terrain that would later be designated as part of the Arctic National Wildlife Refuge and the Arctic Wildlife Refuge Wilderness. The presence of the Leffingwell Fork in the southwest highlights the importance of name-bearing landmarks in this unpopulated expanse, while Redwacke Creek feeds the northern reaches. This survey represents a period of mapping before modern infrastructure reached the area, preserving a view of the land defined entirely by its natural hydrology and the established Base Line surveying marker. The map serves as a primary record of the topography and watercourses as they existed during the initial photogrammetric surveys of the mid-1950s.
