Redoximorphic iron depletions are in the lower part, above 40 inches. It typically is silty clay loam, but the lower part includes silt loam. Clay content is 27 to 35 percent in the upper part and is 24 to 32 percent in the lower part. Reaction is strongly acid to neutral. Clay content is 18 to 27 percent.
Reaction is moderately acid to slightly alkaline.
Eleroy , Rocheport , Stonehead , and Westgate soils have a paralithic contact in the series control section. Slope ranges from 2 to 10 percent. These soils formed in loess. Mean annual temperature is 54 to 57 degrees F., mean annual soil temperature is 56 to 59 degrees F., mean annual precipitation is 36 to 40 inches, frost-free period is 170 to 200 days, and elevation is 400 to 800 feet above sea level. These are the Bethalto , Wakenda , and Winfield soils.
