The town of Summit serves as the central hub of this prairie landscape, situated near the boundary line between Roberts Co and Grant Co. The geography is defined by the Coteau des Prairies, a high plateau that influences the local drainage patterns. Water features are prominent throughout the region, including the headwaters of the Big Sioux River and the Indian River. To the northeast, Mollie Lake sits among the glacial depressions, while Summit Lake and the Twin Lakes occupy the southeastern reaches of the quadrangle.
