1978 Map of Peach Lake

About this map

The Peach Lake region of Dewey County unfolds as a landscape defined by intermittent watercourses and the high ground of the Firesteel terrain. This 1970s survey, conducted just before its publication in the late seventies, illustrates the sparse drainage network typical of the Cheyenne River Indian Reservation. The map tracks the winding paths of Meadow Creek as it meanders across the central and southern sections, while Redwater Creek drains the eastern portion of the quadrangle. In the southwest, the headwaters of Red Earth Creek provide a localized look at the area's hydrology. The small, named body of Peach Lake serves as a primary landmark in an otherwise open prairie environment, offering a clear reference point for those studying the physical geography of this portion of South Dakota.
