1983 Map of Demarcation Point A-5

USGS Topo · Published 1983

About this map

Mount Isto stands as the prominent landmark within the Romanzof Mountains, anchor of this high-latitude terrain. This 1983 edition, based on earlier photogrammetric surveys, documents the glacial extent of the Arey Glacier and Schwanda Glacier before modern shifts in ice coverage. The landscape is defined by the Continental Divide, which separates the north-flowing headwaters of the Jago River and Aichilik River from the drainage of the Sheenjek River to the south. Located entirely within the Arctic National Wildlife Refuge, the area highlights a wilderness state where no roads or trails were recorded, reflecting the topographical complexity of the eastern Brooks Range during the late twentieth century.
