1972 Map of Coleen D-6

USGS Topo · Published 1974

About this map

Shoulder Mountain dominates the central landscape of this 1970s interior Alaska survey, rising above the convergence of major glacial waterways. The topographical data, derived from 1972 aerial photography, reveals a rugged wilderness defined by the winding course of the Koness River as it joins the broader Sheenjek River valley. This confluence creates an intricate network of braided channels and wetlands, illustrating the dynamic hydrology of the Yukon-Koyukuk region before contemporary shifts in drainage patterns. The map also delineates the North Boundary Fairbanks Meridian, marking a critical point for land administration in an area otherwise devoid of permanent roads or settlements. This sheet is essential for understanding the pristine state of the eastern Brooks Range foothills during the early 1970s.
