2023 Map of Demarcation Point B-4 NE

About this map

Arctic National Wildlife Refuge and the Mollie Beattie Wilderness encompass this remote stretch of the North Slope, where the drainage patterns of the Aichilik River define the landscape. This 2023 survey provides a clear view of the river's braided channels as it flows north, joined by the Leffingwell Fork in the southern sections. The map is primarily a study of topography and hydrology within protected wilderness boundaries, showing the complex contouring of the Brooks Range foothills. While devoid of permanent settlements or roads, the map serves as a vital record of the untouched terrain within the nation's largest wildlife refuge, documenting the natural state of the watershed and the vast public land survey system divisions across the North Slope Borough.
