1918 Map of White Rock

About this map

Lake Traverse and the Bois de Sioux River dominate this tri-state borderland where South Dakota, Minnesota, and North Dakota converge. The 1915 survey captures a landscape structured by rural township schools and early rail expansion, including the Chicago Milwaukee and St Paul and the Minneapolis Sault Ste Marie and Atlantic. The northern boundary of the Sisseton and Wahpeton Indian Reservation cuts through the center of the sheet, defining land use patterns near Rosholt and White Rock. A dense network of local education is evident through family-named institutions like Knutson School, Teare School, and Norburg School. The eastern portion of the map shows the meandering Mustinka River feeding into the lake near the Wheaton settlement, illustrating the importance of these water systems to early regional development.
