1968 Map of Orinoco

About this map

The Yellowstone River serves as the central artery of this Montana landscape, where the braided river channel dictates the layout of the region's transportation and irrigation infrastructure. The settlement of Orinoco sits along the northern bank, closely tied to the path of the Burlington Northern railroad and the Burlington Northern Canal. This era of the late 1960s shows a landscape defined by water management and transit, with numerous creeks and coulees such as Little Porcupine Creek and Wildcat Coulee draining into the main valley. Further south, the presence of Tillit Field and a highway Weigh Station highlights the intersection of local aviation and regional commerce. The northern plains above the river valley are dissected by drainage systems like Horse Creek and Dry Creek, illustrating the transition from the fertile river bottoms to the higher, arid ranching lands of Rosebud County.
