2020 Map of Cannon Ball SW

About this map

Cannon Ball anchors the eastern edge of this landscape in the Standing Rock Reservation, where the terrain is defined by a network of seasonal drainages cutting through the prairie. The hydrology of the region is traced by the winding paths of Beaver Holes Cr, Fool Bear Cr, and Battle Cr, which reveal the natural erosion patterns of the Missouri River plateau. The road system follows a strict township and range grid, with rural routes such as S Big Lake Rd, 80th St, and 14th Ave providing access to the isolated homesteads and grazing lands. This 2020 survey illustrates how modern infrastructure remains tethered to the section lines established over a century ago, maintaining a sparsely populated character where geography is primarily dictated by the flow of water toward the larger river basins to the east.
