Buffalo Ridge is a large expanse of rolling hills in the southeastern part of the larger Coteau des Prairies. It stands 1,995 feet (608 m) above sea level. The Buffalo Ridge is sixty miles (97 km) long and runs through Lincoln, Pipestone, Murray, Nobles, and Rock counties in the southwest corner of Minnesota, and Minnehaha, Moody, and Lincoln counties in southeast South Dakota.

Because of its altitude and high average wind speed, Buffalo Ridge has been transformed into a place for creating renewable energy. As of May 2022, over 1,000 wind turbines stand in the Buffalo Ridge area.[1]

Buffalo Ridge is located within the Minnesota portion of the Coteau des Prairies, a highland represented by the light areas in this shaded relief image of southwestern Minnesota.

Geology

Buffalo Ridge is on a

drainage divide separating the watersheds of the Mississippi and Missouri Rivers
.

Buffalo Ridge is part of the inner

dendritic drainage networks, the majority of which flow into the Missouri River and Minnesota River
systems.

Ustolls dominate the soils of the inner coteau.[3] On the areas of eroded glacial deposits, dry prairie and moist prairie soils like Cummins and Grigal are present. These soil types, along with the temperate climate,[5] combine to make perfect growing conditions for tallgrass prairie
, which once covered almost the entire inner coteau.

Climate

Buffalo Ridge has a midlatitude continental climate with an average 24 to 27 inches (61 to 69 cm) of precipitation per year and 36 to 40 inches (91 to 101 cm) of snowfall per winter. The average spring thaw is around April 5 and the spring green-up generally occurs between May 1 and May 10. Peak fall colors usually occur around October 20 and there are generally 40 to 50 thunderstorm days per year.[6]

Chandler–Lake Wilson, Minnesota F5 tornado of 1992

On June 16, intense storms struck

Fujita Scale, making it the only F5 tornado documented in the United States in 1992. Another tornado formed in South Dakota later in the day, striking Colton and Dell Rapids before moving into Minnesota, where it struck the town of Chandler for the second time.[citation needed

Geography

Before the settlers arrived and developed the towns on and surrounding Buffalo Ridge, the Dakota Native Americans inhabited the area. They, and other tribes before them, created intricate pipes out of the claystone called "Catlinite" in the Buffalo Ridge area, which are displayed at Pipestone National Monument. Native Americans from around the country still quarry this stone for pipe-making today.

Most of the land on Buffalo Ridge is privately-owned farmland.

controlled burning which have led to a remarkable recovery of the native prairie vegetation.[7]

Wind farms

A number of

wind farms are sited on the ridge. Among them are Nobles Wind Farm, Buffalo Ridge Wind Farm
, and Fenton Wind Farm.
