About this map

The Cheyenne River carves a deep path through western South Dakota, defining the landscape of this 1954 survey for the Missouri River Basin development program. The topography is dominated by extensive plateaus known locally as tables, including Quinn Table, Scene Table, and Kube Table, which overlook the river valley and its surrounding flats. These elevated plains represent the distinct geological character of Pennington County, where drainage systems like Beaver Creek and Farnum Draw have eroded the land into a complex network of ridges and draws.

Evidence of rural community life and early ranching infrastructure appears in the placement of Centerville Sch and several Windmills scattered across the higher ground. The map captures the area between Holcomb Flat and Brennan Flat at a time when the region was primarily dedicated to open-range agriculture and small-scale schooling, just as modern water management programs began to reshape the Missouri River's tributaries. Near the northern boundary, the proximity to Owanka marks the edge of more settled territory.
