About this map

Coteau des Prairies defines the elevated landscape of this South Dakota region, where the high ground of the plateau meets the drainage of the Big Coulee. The small settlement of Spring Grove serves as a local focal point, surrounded by evidence of early community life in the Old Agency District. This area preserves distinct cultural sites such as the Old Ascension Cem and the nearby Ascension Presbyterian Cem, reflecting the spiritual and genealogical history of the Sisseton Wahpeton Oyate lands. The topography is intricately carved by Big Spring Cr and Big Coulee Cr, which draw from the Big Spring at the northern edge of the sheet. A network of rural routes, including Indian Rte 200 and Indian Rte 1100, connects these remote highlands, illustrating the modern management of tribal and public lands.
