The settlement of Grant sits at the southern edge of this western Montana landscape, positioned where Barrett Cr meets the larger Horse Prairie Cr. This high-country basin is defined by an intricate network of irrigation systems, reflecting a long history of ranching and water management. Named features like the Hans Peterson Ditch, Prohosky Ditch, and Jagger Ditch cut across the valley floor, diverting water to support the Horse Prairie area.
