Reaction ranges from moderately acid to neutral. The 2Btg, 2Bt, 2BCg, or 2BC horizons have hue of 10YR, 2.5Y, 5Y, or are neutral, value of 4 to 6, and chroma of 0 to 4. They are clay, silty clay, clay loam, or silty clay loam. Clay content ranges from 27 to 42 percent. Rock fragment content ranges from 1 to 10 percent.
Reaction ranges from neutral to moderately alkaline.
The 2C or 2Cg horizon has hue of 10YR, 2.5Y, or 5Y, value of 4 to 6, and chroma of 1 to 6. Texture and rock fragment content are similar to the 2B horizon. Reaction is slightly alkaline or moderately alkaline and contains carbonates. There are no other series in this family.
