1968 Map of Orinoco

About this map

The Yellowstone River cuts a wide path through this portion of Rosebud County, Montana, defining a landscape of irrigation and heavy transport in the late 1960s. The northern bank is marked by the small settlement of Orinoco and the Cartersville Canal, which draws water from the river to support local agriculture. The importance of this corridor for regional movement is evident in the parallel alignments of the Chicago Milwaukee St Paul and Pacific and Burlington Northern railroads, which hug the river's path. To the south, the Lewis and Clark Trail and a local Weigh Station highlight the modern highway system’s role. The terrain transitions from the alluvial bottomlands of Flynn Island to the dissected uplands carved by Little Porcupine Creek and Wildcat Coulee, where a network of pipelines and service roads suggests the region's energy infrastructure and ranching activity.
