1961 Map of Coburn Mountain

USGS Topo · Published 1979

About this map

The Dearborn River carves a winding path through the borderlands of Cascade and Lewis and Clark counties, where ranching and early infrastructure define the mountain landscape. The presence of the Dearborn Ranch and the Dearborn Cem reflects a community anchored to this river valley. Prominent terrain features like the long ridge of Elephant Mountain and the craggy formation of The Reef dominate the western half of the sheet, while Coburn Mountain rises to the southeast. Technical development is evident in the 1960s landscape, seen in the pipeline corridor and a Pumping Station situated near the river. Along the Sevenmile Road, the Sevenmile Sch stands as a vital touchstone for local history, marking the site of early rural education in this high-plains transition zone.
