Texture is silty clay loam or silt loam. Reaction naturally ranges from very strongly acid to slightly acid but ranges to neutral in the upper part in some pedons, where the soil is limed. The 2Bt horizon has hue of 7.5YR or 10YR, value of 3 to 5, and chroma of 4 to 6. Texture of the 2Bt is clay loam, sandy clay loam, loam, fine sandy loam, or sandy loam or the gravelly analogs. Carbonates are present in some pedons.
Reaction ranges from moderately acid to slightly alkaline.
Some pedons have a 2Btk or 2BCtk horizon with colors like the 2Bt horizon. Texture is sandy loam, fine sandy loam, or the gravelly analogs. These horizons contain identifiable secondary carbonates. Reaction is slightly or moderately alkaline. Value is 5 or 6 and chroma is 3 or 4.
