About this map

The Missouri River winds through this 1940s landscape, serving as a natural boundary between Brule and Lyman counties. This era of the river's history shows large riverine features like Bailey Island and Phillips Island before major mid-century dam projects altered the Missouri's flow. Along the northern edge, the White River joins the Missouri, framed by the plateau of Petersons.
