2023 Map of Demarcation Point A-4 NW

About this map

The Romanzof Mountains dominate this high-latitude terrain within the Arctic National Wildlife Refuge. This particular landscape is defined by its extreme isolation and dramatic elevation changes, where the peaks of the Romanzof range give way to the headwaters and drainages of the north-flowing Aichilik River. Located in the northeast corner of the North Slope, the area is largely protected within the Mollie Beattie Wilderness, ensuring that the natural survey lines remain focused on the hydrology and topography of the Brooks Range foothills. The map reveals the intricate drainage patterns that feed into the Arctic coastal plain, showing how the seasonal movement of water across the tundra is dictated by the massive uplift of the Romanzof peaks.
