2018 Map of Demarcation Point B-5 SW

About this map

Mt Hubley and Mt McCall dominate this high-latitude terrain within the Romanzof Mountains, part of the Brooks Range in Alaska's far north. This 2018 survey details a landscape of extreme verticality, where deep glacial features like Bur Cirque and prominent ridges such as the Wolverine Crags define the drainage patterns. The Okpilak River winds through the Okpilak Valley in the west, while McCall Cr cuts through the center of the quadrangle. Several high peaks are named for individuals, including Schwanda Peak and Contact Peak, suggesting a history of specialized alpine exploration and scientific study in this glaciated environment. The map provides a precise record of these features as they existed in the early 21st century, prior to further shifts in the Arctic's cryosphere.
