Surface runoff potential is medium or rapid. At undisturbed sites there is a perched water table at depths of 0 to 1.0 feet during the spring in most years. These soils are seasonally wet and seepy. Most areas are used for pasture or for forages that are cut for hay. Cultivated crops are on some of the less sloping areas.
Native vegetation is prairie grasses.
Western and northwestern Illinois. Stephenson County, Illinois, 1969. The variability of the properties in the Coatsburg series is related to the geologic truncation of the paleosol before it was buried by loess, and to the extent that modern soil forming processes have altered the paleosol. Many of the properties of the 2Btg horizon are believed to have been inherited from the paleosol. It is difficult to differentiate the properties of the lower part of the modern soil from those of the paleosol in many pedons.
