Dissected Till Plains

The Dissected Till Plains are physiographic sections of the Central Lowlands province, which in turn is part of the Interior Plains physiographic division of the United States, located in southern and western Iowa, northeastern Kansas, the southwestern corner of Minnesota, northern Missouri, eastern Nebraska, and southeastern South Dakota.

The Dissected Till Plains were formed by pre-Wisconsin glaciations during the Pre-Illinoian Stage. Glacial scouring and deposition by the Laurentide ice sheet and the later accumualtion of loess during the Wisconsin Stage left behind the rolling hills and rich, fertile soils found today in the region.

Northern Plains is a region in the state of Missouri and is part of the larger Dissected Till Plains region. It lies north of the Missouri River and stretches into Iowa, Nebraska and Kansas. Here, gentle rolling hills remain behind from a glacier that once had extended from the north to the Missouri River.

The region is also the western edge of the Corn Belt.
