The Bx horizon has hue of 10YR or 7.5YR, value of 5 or 6, and chroma of 4 through 8 and normally has many grayish and brown mottles. Texture is silt loam or silty clay loam in the fine-earth fraction and has medium or coarse angular or subangular blocky arranged in very coarse prisms to medium or thick platy structure. Fragipan expression is weak or moderate. Some pedons have friable to firm silt loam to silty clay BC horizons below the fragipan. The C horizon has hue of 10YR through 5YR, value of 2 through 6, and chroma of 2 through 8.
Texture ranges from loam to clay in the fine- earth fraction.
Some pedons have 2C horizons containing high amounts of shale. The Chalfont , Haubstadt , Lawrence , Pekin , Robbs , Rohrersville , Rossmoyne , Sciotoville , and Shakamak series are in the same family. Chalfont soils have a lithologic discontinuity with a distinct increase in rock fragments within the series control section. Haubstadt and Shakamak soils have sola more than 60 inches thick. Lawrence, Pekin, Rossmoyne, and Sciotoville soils have strongly to very strongly acid Bt horizons.
