About this map

The Missouri River and Big Sioux River define the tri-state convergence where Iowa, Nebraska, and South Dakota meet during the late twentieth century. This region is anchored by Le Mars and the academic campuses of Briar Cliff College and the University of South Dakota. The landscape transitions from the river bottomlands, featuring Mc Cook Lake and Burbank Lake, to the upland prairies marked by topographic landmarks like Spirit Mound and Volcano Hill.

Rail transport remained a vital element of the local economy during this era, with the Illinois Central Gulf and Chicago and North Western corridors connecting agricultural hubs like Orange City and Akron. Recreational and conservation lands are well-established, including Stone State Park and Ponca State Park, alongside numerous Gravel Pits that suggest ongoing local industry. Smaller settlements such as Oyens, Struble, and Chatsworth provide a detailed look at the rural distribution of the tri-state area before the turn of the millennium.
