2018 Map of Demarcation Point A-4 NE

About this map

The Aichilik River defines the northwestern reaches of this interior North Slope terrain, cutting a path through a landscape of high-elevation contours. This 2018 survey serves as a fundamental record of the drainage patterns and land-survey divisions within the Brooks Range foothills, specifically capturing the intersections of the townships of t2s r38e, t3s r38e, and t4s r38e. The absence of developed roads, settlements, or infrastructure emphasizes the topographical nature of this quadrant, where the primary data points are the natural hydrography and the established Public Land Survey System boundaries. For those studying the northernmost wilderness of Alaska, the map provides precise elevation data and the alignment of the river system before it continues its journey toward the Beaufort Sea.
