About this map

Arctic National Wildlife Refuge encompasses this entire northern landscape, a high-altitude wilderness where the Brooks Range begins its descent toward the Beaufort Sea. The terrain is defined by dramatic elevation changes, culminating at the summit of Marie Mtn. This remote corner of the Mollie Beattie Wilderness is carved by glacial drainage systems, with the Okpilak River and Jago River flowing northward through deep valleys. These watercourses are fed by high mountain tributaries like Okpirourak Creek and McCall Creek, illustrating the raw hydrological patterns of the Alaskan North Slope. The absence of roads or man-made structures highlights the protected nature of this environment, preserving the exact topographical character of the land as it has existed for millennia.
