What mountain ranges are in the midwestern states?

The Midwest is primarily characterized by flat plains, but it does feature some notable mountain ranges. The Ozark Mountains, located in southern Missouri and northern Arkansas, are the most prominent range in the region. Additionally, the Black Hills in South Dakota and the Appalachian Mountains' foothills extend into parts of the Midwest. However, these ranges are generally less significant compared to the mountainous regions found in other parts of the United States.
