About this map

The Grand River meanders across the southern portion of this landscape in Corson County, shaping the local topography as it flows eastward. This segment of the river valley is defined by its dramatic bends and the confluence with High Bank Cr, which drains the southern bluffs. The map captures the systematic organization of the rural South Dakota prairie, where a grid of section lines and gravel roads such as 258th Ave and 259th Ave partition the open country. Along the river corridor, specialized routes like Grand River Rd and Bia Rd 4 provide access to the riparian areas and bottomlands. The terrain transitions from the river's low-lying floodplain to the higher, undulating plains of the north, illustrating the characteristic drainage patterns of the Standing Rock reservation area.
