About this map

Three Forks sits at the vital hydrological nexus where the Jefferson River, Madison River, and Missouri River converge. This 1980s-era Montana landscape reflects a complex arrangement of water-driven geography and industrial infrastructure. The town itself is defined by its agricultural and transit heritage, evidenced by the presence of a Grain Elevator, Storage Bins, and a substantial Feed Lot near the rail lines.

North of the rivers, the terrain transitions into a series of gulches and ridges, including Mud Spring Gulch, where several Mine Shafts and prospects indicate a history of small-scale mineral extraction. Transport history is visible through the Old RR Grade winding through the valley floor, while a Gaging Station monitors the heavy water flow of the river confluence. The boundary between Broadwater Co and Gallatin Co cuts across the wetlands where the three rivers meet to form the Missouri.
