About this map

The Clark Fork river serves as the central artery for this western Montana landscape, shaping the agriculture and settlement patterns of the Missoula valley. Large-scale irrigation efforts are prominent, evidenced by the Frenchtown Irrigation District Ditch, Grass Valley French Ditch, and Big Flat Ditch, which channel water across the valley floor to support the region's farms. These water systems define the layout of rural communities like Schilling, Primrose, and Grass Valley, where small-town life meets the industrial transport corridor of the Interstate and railroad lines.

Rising above the valley floor, the rugged slopes of the Lolo National Forest are marked by numerous ravines, including Cyr Gulch, Dry Gulch, and Sherman Gulch. This interface between the protected timberlands and the developed valley provides a clear view of the geographic limits of urban growth near Missoula, where local landmarks like Harper Bridge connect the residential and agricultural areas across the river's path.
