About this map

The glacial landscape of the Coteau des Prairies defines this portion of Minnehaha County, characterized by a complex network of wetlands and small water bodies. High ground separates numerous depressions, including Grass Lake, Lost Lake, and several named marshes such as Englehardt Slough and Fensterman Slough. This section of the coteau drains through small seasonal channels like Long Cr and Elce Cr, illustrating the subtle hydrology of the eastern South Dakota plains.

Local history is anchored by the small communities and religious sites that dot the grid of section roads. The settlement of Pumpkin Center serves as a central landmark, while the Saint Joseph Catholic Cem and German Methodist Cem provide important reference points for genealogical research. Further south, the label for Rocky Ridge marks a distinct topographical feature amidst the agricultural fields and drainage ways of Beaver Cr.
