2021 Map of Miscol NE

About this map

The Grand River snakes through the northern reaches of Corson County, carving a deep, wandering path across the South Dakota landscape. This 2021 topographic map documents the river’s complex meanders and the surrounding drainage systems of the Missouri Plateau. A notable tributary, Plum Cr, flows into the river from the south, marking a significant break in the uplands. The terrain is characterized by the intricate contouring of coulees and breaks that define the river valley, illustrating the erosion patterns typical of this region. The absence of modern development highlights a landscape dominated by the Public Land Survey System, with township and range lines like t21n r25e and t20n r24e providing the primary structure for land division in this open country.
