2023 Map of Demarcation Point B-4 SE

About this map

The Romanzof Mountains dominate this high-latitude terrain within the Arctic National Wildlife Refuge, where sharp relief and steep drainage basins define the landscape. This 2023 edition shows the north-flowing Aichilik River cutting through the western portion of the sheet, while the Leffingwell Fork occupies the northeast corner. These watercourses are vital components of the protected ecosystem within the Mollie Beattie Wilderness, representing a preserved Arctic environment where natural processes remain largely undisturbed by human infrastructure. The lack of roads or established settlements emphasizes the character of this part of the North Slope Borough, where land management is focused on conservation and wilderness preservation.
