The Big Hole River carves a winding path through this corner of Montana, serving as the geographic boundary between Deer Lodge Co and Beaverhead Co. The landscape is defined by its sophisticated irrigation network, with long-established waterworks like the Ampo Toomey Ditch, Seefeld Ditch, and Nichols Ditch distributing water from mountain creeks to the valley floor. These systems supported isolated family operations such as Bacon Ranch and Nichols Ranch during the mid-20th century.
