2017 Map of Lone Man Coulee West

About this map

The Dry Fork Marias River and its northern tributary, the N Fork Dry Fork Marias River, carve a complex drainage system across this Montana landscape. The terrain is defined by prominent elevations such as Frances Heights and Black Buttes, while numerous coulees, including Lone Man Coulee and Miller Coulee, indicate the erosive power of seasonal runoff in this semi-arid environment. The road network reflects a remote agricultural and ranching layout, with long stretches like Conrad Dupuyer Rd and Skyview Rd N connecting disparate parcels. A notable cultural feature is New Miami Colony Ln, signifying the localized presence of communal farming settlements in the region. The map also captures the boundary between Pondera and Teton Counties, where land use transitions near features like Coalmine Rd and the aptly named Sagebrush road.
