2018 Map of Demarcation Point A-5 NW

About this map

The Romanzof Mountains dominate this high-latitude terrain within the Brooks Range, rising sharply above the glacial valleys of the far north. This 2018 survey captures a landscape defined by extreme elevation and ice, most notably at Mt Isto, which stands as a prominent peak in the eastern portion of the range. The Okpilak River carves a deep path through the Okpilak Valley, illustrating the powerful hydrological forces that shape this arctic environment. The lack of human settlements or infrastructure emphasizes the wilderness character of the North Slope, where the topographic detail reveals the intricate ridges and drainage patterns of the Romanzof subrange. For researchers and geologists, this map provides an exacting look at the structural geology and perennial snowfields of one of the highest regions in the American Arctic.
