Spring Valley occupies a central position within this Montana landscape, where the drainage patterns of the Missouri River watershed define the local geography. The area is characterized by the convergence of several waterways, including the West Fork Little Porcupine Creek and the East Fork Little Porcupine Creek, which join to form Little Porcupine Creek. These creek valleys create natural corridors through the high plains of Valley County, historically influencing movement and settlement in the region.
