2018 Map of Demarcation Point B-1 SE

About this map

Clarence River flows through this 2018 survey of the northeastern corner of the North Slope Borough, just west of the international boundary. This remote Arctic landscape is defined by the high-elevation drainage basins of the Pagilak River and its mountain tributaries. The map documents the complex topography of the eastern Brooks Range foothills, showcasing the intricate ridgelines and narrow valleys of the North Slope. Lacking any roads, trails, or permanent structures, the terrain is represented purely through its hydrologic network and 40-foot contour intervals, capturing the primitive state of the United States border region in the early twenty-first century.
