Prairie, often considered a featureless flatland, actually contains great diversity, reflecting the depositional features associated with the Wisconsinan GLACIATION. Topography ranges from broad undulating plains to rolling hills and plateaus, often dissected by beautiful valleys and escarpments.
This is a steep or vertical cliff which usually extends over a considerable distance. The most common type of escarpment occurs where more resistant strata form a cap rock over easily eroded rocks. As EROSION takes place, the lower rock erodes more rapidly so that the cliff remains very steep.
