1964 Map of Mountain House

About this map

Bitterroot National Forest dominates the southern half of this map, where the terrain transitions from the developed valley floor to steep, gulch-carved mountains. The lower elevations near Hamilton Airport and the Hamilton Golf Course reveal a sophisticated water management system designed to support agriculture in the high desert of Ravalli County. Large-scale infrastructure like the Bitterroot Irrigation District Canal, Ward Ditch, and Hedge Ditch cut across the landscape, while the Skalkaho High Line Ditch and Skalkaho Aqueduct navigate the more difficult terrain to the east. These canals and aqueducts represent the vital lifelines of the local ranching and farming economy during the mid-1960s.
