Most of the surrounding area is flat , and the elevation ranges from 169 metres ( 554 ft ) and 281 metres ( 922 ft ) above sea level . The soil mostly comprises clay . Despite this high percentage of clay , the soil is remarkably rich for cultivation . Prior to the Ice Age , glaciers covered most of the area , as can be seen not only by the existence of the Great Lakes themselves but also of alluvial sand deposits, terminal moraines, and rich oil reserves."
