1918 Map of White Rock

About this map

Lake Traverse and the Bois de Sioux River form the focal point of this 1915 survey, marking the intersection of South Dakota, Minnesota, and North Dakota. This tri-state landscape is defined by the Sisseton and Wahpeton Indian Reservation in the west and a dense network of early rural schoolhouses that served the agricultural community. Settlements like White Rock and Rosholt are positioned along competing rail lines, including the Chicago Milwaukee and St Paul and the Minneapolis Sault Ste Marie and St Paul. The map provides a detailed look at the water-management of the era, showing the Big Slough and the Mustinka River feeding into the lake valley. For genealogists, the inclusion of named school sites such as Teure School, Knutson School, and Norburg School offers a precise look at the educational infrastructure of Roberts and Traverse counties before the mid-century consolidation of rural districts.
