1918 Map of White Rock

About this map

Lake Traverse and the Bois de Sioux River anchor this 1915 survey of the tri-state border region where South Dakota, North Dakota, and Minnesota converge. The landscape is a testament to the early 20th-century agrarian settlement, marked by an exceptionally dense grid of rural schools like the Teare School, Knutson School, and Moreland School. These one-room schoolhouses served the families farming the expansive flats between the Big Slough and the Mustinka River.
