A narrow band of unusual hills skirts the Missouri River valley along Iowa's western border. The steep, sharply ridged topography and the predominance of native grass and woodland cover stand in marked contrast to the orderly rolling farm fields to the east and the broad cultivated floodplain of the Missouri River to the west. These high, narrow-spurred ridges, steep slopes, and deep ravines constitute the Iowa landform region known as the Loess Hills.
