The depth to the fragipan ranges from 18 to 30 inches in uneroded pedons. Rock fragments are less than 2 percent in the loess mantle and increase to 2 to 15 percent in the underlying glacial till. They are commonly silt loam but the Ap horizon in eroded pedons ranges to silty clay loam. They are strongly acid or very strongly acid except the Ap ranges to neutral. The E horizon has hue of 10YR or 7.5YR, value of 5 or 6, and chroma of 2 or 3.
Texture is silt loam.
Reaction is strongly acid or very strongly acid. The Bt horizon has hue of 10YR or 7.5YR, value of 4 or 5, chroma of 4 to 6, and iron depletions of low chroma within the upper 10 inches. It is silty clay loam or silt loam with 25 to 35 percent clay in the particle size control section. The proportion of sand and small pebbles increases gradually in and near the lithologic discontinuity. Some pedons have a 2Bt horizon in glacial till or loamy pedisediments above the fragipan that ranges to clay loam or loam.
