1981 Map of Ismay North

About this map

The Chicago Milwaukee St Paul and Pacific railroad cuts a diagonal path through this Montana landscape, connecting the small settlement of Ismay to the wider region. This 1981 survey documents the semi-arid drainages where O'Fallon Creek meets tributaries like Pennel Creek, Ash Creek, and Malone Creek. The terrain is marked by the presence of several Flowing Wells and resource extraction sites, including a Drill Hole and multiple Gravel Pits. A notable Pipeline and a Storage Bin suggest the area's role in industrial transport and agricultural storage. The county line between Prairie Co and Custer Co bisects the northern section of the map, illustrating the administrative divisions of this ranching and rail territory.
