About this map

Dempster anchors the southern portion of this South Dakota landscape, situated along the line of the Chicago and North Western railroad. The terrain is defined by the winding course of the Big Sioux River and its tributaries, including Horse Creek and Stony Creek. In the northeast, the rural community life of the late 1960s is centered around landmarks like Bemis Ch and Bemis Cem, while Hamlin Ch serves the central region.

A notable engineering feature is the Boswell Diversion Ditch, which redirecting water near the river's western bank. The map also records industrial and land-use details such as scattered Gravel Pits and the Deuel Wood area near the Hamlin Co Deuel Co border. Red dashed lines throughout the quadrangle provide an unusual level of detail, indicating specific fence and field lines visible from aerial photography during the 1966 photogrammetric survey.
