1968 Map of Big Hill

About this map

The Yellowstone River anchors this 1968 landscape, flowing past the southwestern edge of a territory defined by expansive ranching and federal lands just west of Miles City. The Old Fort Keogh Military Reservation Boundary cuts across the southern portion of the map, marking a significant historical land use transition that by this era supported the Range Experimental Station. The topographic character is shaped by a dense network of drainages including South Sunday Creek, North Sunday Creek, and Cottonwood Creek, which carve out the rugged breaks around the prominent Big Hill. Transportation and infrastructure are central to the area's utility, with the Chicago Milwaukee St Paul and Pacific and Burlington Northern railroads paralleling the river, while the Miles City Municipal Airport occupies the plateau to the east.
