1955 Map of De Long Mountains

USGS Topo · Published 1964

About this map

Cape Sabine and Corwin Bluff mark the coastal boundary where the Chukchi Sea meets the northwestern edge of the Brooks Range. This mid-century survey illustrates a remote landscape dominated by the De Long Mountains, where numerous river systems like the Pitmegea River, Kukpowruk River, and Wulik River carve through the high terrain toward the Arctic Ocean. Evidence of human activity is sparse but significant, centered on the Winter Trail that skirts Agiak Lagoon and the isolated Thetis Mine located near Thetis Creek. The map provides a detailed look at the drainage patterns of the Beaufort Basin and the distinct peaks of Noonuklook Mountain and Mount Kelly, documenting the geography of the North Slope before modern development altered these traditional transit corridors.
