The clay content ranges from 30 to about 50 percent but the control section averages 35 to 42 percent clay. The calcium carbonate equivalent ranges from 15 to 40 percent. The COLE ranges from about .04 to .09 in the upper 50 inches but lacks a layer 20 inches or more thick with COLE OF .07 or more. Some pedons contain limestone and chert pebbles or cobbles that make up less than 15 percent by volume. The A horizon has hue of 7.5YR or 10YR, value of 3 to 5, and chroma of 2 or 3.
Texture is silty clay, silty clay loam, or clay loam.
Some pedons have light colored discontinuous loamy strata less than 3 inches thick. Most pedons have a B horizon with greater value or chroma than the A horizon. It is below a depth of 22 inches and typically below the control section. However, some pedons have buried A horizons at these depths. The soil material above the buried A horizon is probably post-settlement alluvium.
