Nasset soils commonly are upslope or farther from the drainageways. Elizabeth soils have a lithic contact within a depth of 20 inches.
Surface runoff is medium or rapid.
Permeability is moderate in the loess and slow in the residuum. Many of the less sloping areas are used to grow corn, small grain, forage crops. Steeper slopes are used as pasture or woodland. Native vegetation is hardwood trees, chiefly oak and hickory. Unglaciated parts of northwestern Illinois, southwestern Wisconsin, northeastern Iowa, and southeastern Minnesota.
