1915 Map of White Rock

About this map

Lake Traverse and the Bois de Sioux River anchor this 1915 survey of the tri-state junction where South Dakota, Minnesota, and North Dakota meet. The landscape is defined by the Sisseton and Wahpeton Indian Reservation boundary, which cuts across the prairie west of the river. The region's early 20th-century agricultural development is evident through a dense network of country schools, including the Taylor School, Teare School, Knutson School, and Norburg School, serving the surrounding townships of Lamars and White Rock.
