1955 Map of De Long Mountains D-1

About this map

Poko Mountain dominates the central landscape of this mid-century survey, rising above a network of northern waterways and unmarked land lines. The Kokolik River winds through the eastern portion of the sheet, joined by the Tingmerkpuk River and various unnamed tributaries that drain the surrounding high ground. Topography was established by photogrammetric methods from 1955 aerial photography, reflecting the wilderness state of the region during the post-war era of Arctic mapping. Scattered landmark points like Ginn and Poko provide specific surveying references across the terrain. Notable for its lack of roads or established settlements, the map illustrates the remote drainage patterns of Tupikchak Creek and Surprise Creek as they existed before modern development or resource extraction altered the North Slope's natural drainage basins.
