2018 Map of Demarcation Point A-3 SW

About this map

Drain Cr meanders through the high-latitude terrain of the North Slope, illustrating the hydrologic patterns of the Alaskan arctic before it reaches the Beaufort Sea. This 2018 survey by the U.S. Geological Survey provides an intricate look at the land's elevation through dense contouring, revealing a landscape defined by sharp ridges and deep drainage basins. The lack of man-made structures or named settlements highlights the extreme isolation of this quadrangle within the North Slope Borough, where geography remains dictated by natural drainage systems and seasonal freeze-thaw cycles. Collectors and researchers can study the intricate topography across t4s r39e and t4s r40e, where the terrain's geometry reflects the unique geomorphology of the Brooks Range foothills.
