Rock fragment content ranges from 2 to 10 percent by volume. Reaction is neutral to moderately alkaline. The Cg or C horizon has hue of 10YR to 5Y, value of 4 to 6, and chroma of 1 to 6. It is clay, silty clay, silty clay loam, or clay loam with clay content of 27 to 42 percent. Rock fragment content ranges from 2 to 10 percent by volume.
Reaction is slightly alkaline or moderately alkaline.
Calcium carbonate equivalent ranges from 15 to 30 percent. These are the Lorain , Miner and Monee series. Lorain and Monee soils have less than 2 percent rock fragments in the lower part of the series control section. Miner soils have calcium carbonate content of less than d15 percent in the lower part of the series control section. Hoytville soils occur on broad flats and depressional areas on till-floored lake plains of late Wisconsin age.
