1970 Map of Summit

About this map

The town of Summit serves as the focal point of this 1970 prairie survey, situated where the Chicago Milwaukee St Paul and Pacific railroad grade intersects the Coteau des Prairies. This landscape is a complex patchwork of glacial potholes and wetlands, including Mollie Lake and the headwaters of the Big Sioux River. The map meticulously records the intersection of human and natural boundaries, from the Sisseton Indian Reservation Boundary and township lines like Farmington and Ortley to the protected wetlands of the National Wildlife Management Area. For genealogists and local historians, the sheet provides detailed locations for the Summit Cem and outlying farmstead infrastructure, including numerous gravel pits and wells. The wide expanse of Blooming Valley in the southwest contrasts with the lake-dotted terrain of the Osceola and Summit districts, showing the region just as modern highway development was under construction.
