1968 Map of Monida

About this map

Monida sits at a strategic mountain crossing where the Union Pacific railroad and highway infrastructure navigate the high terrain of the Continental Divide. This 1968 survey captures the settlement at the head of the Centennial Valley, serving as a vital link between Montana and Idaho. The landscape is defined by its water management and transit history, from the northern expanse of the Lima Reservoir with its Spillway 6577 to the communication landmarks like the Airway Beacon and Radio Tower Graze that guided travel through Monida Pass. The map details the transition from the ranching and rail-oriented valley floor to the protected slopes of the Targhee National Forest in the south, while numerous named streams such as Beaver Creek and Modoc Creek carve through the high-altitude topography.
