The Sacagawea River winds through this expanse of Fergus County, defining a landscape shaped by intermittent water and essential ranching infrastructure. Central to the map's geography is the Kachia Reservoir, alongside Harri Reservoir to the north, both vital water sources in this semi-arid region. These man-made features are connected by natural drainage patterns, including Antelope Cr and Little Crooked Cr, which underscore the importance of water management in the Big Open country of Montana.
