Grant sits at the heart of this southwestern Montana landscape, serving as a focal point for the ranching and irrigation networks of Beaverhead County. The map details a sophisticated water management system vital to the high-plains economy, including the Paiment Ditch, Jagger Ditch, and Cross Ranch Ditch. These man-made channels divert water from natural flows like Horse Prairie Cr and Dunlap Cr to support the surrounding valley floor. To the northeast, the terrain rises into the Rocky Hills, where Sheep Corral Gulch and Badger Gulch carve through the foothills. Historical movement through the region is traced by routes such as Bannack Bench Rd and the Corinne Trl, connecting the small settlement of Grant to the broader Montana territory. This survey provides a clear look at how land use and water rights have shaped the spatial organization of this specific corner of Horse Prairie.
