1956 Map of Demarcation Point B-4

USGS Topo · Published 1984

About this map

Arctic National Wildlife Refuge dominates this terrain on the North Slope, where the drainage systems of the Aichilik River and Okerokovik River carve through high-altitude topography. This mid-century data, later revised to reflect the established Arctic Wildlife Refuge Wilderness, documents a landscape without roads or permanent settlements. The eastern portion of the sheet is defined by the Leffingwell Fork, which joins the main Aichilik channel amidst complex contour lines. This survey captures the remote character of the Brooks Range foothills before modern environmental designations were fully integrated into the cartographic record, showing the pure hydrology and relief of the Alaskan arctic. The presence of the Base Line crossing the center of the quadrangle highlights the systematic effort to survey these unsurveyed and unmarked lands predetermined by the Bureau of Land Management.
