1950 Map of Three Forks

About this map

Three Forks sits at the hydrologic heart of Montana, where the confluence of the Jefferson River, Madison River, and Missouri River defines the landscape. This mid-century survey illustrates a complex web of water management and transportation essential to the ranching economy. A dense network of irrigation channels like the Francis Ditch and Walbert Ditch crisscrosses the river valleys, supporting prominent operations such as the Climbing Arrow Ranch and Buttleman Ranch. The infrastructure of the era is anchored by two major rail lines: the Northern Pacific and the Chicago Milwaukee St Paul and Pacific, which intersect near the town center. Local history is preserved in rural landmarks including Jefferson Sch, Mt Green Cem, and the Stateler Monument, while industrial activity is noted at the Mine (Open Pit) Copper City and various Gravel Pits along the riverbanks.
