A 2BC horizon, when present, has similar colors as the 2Bt horizon. It is sandy loam, coarse sandy loam or their gravelly or very gravelly analogues. The 3C horizon has hue of 10YR, value of 4 to 6, and chroma of 3 or 4. It is stratified, and textures are dominantly gravelly or very gravelly analogues of loamy coarse sand or coarse sand, and includes strata of loamy sand, coarse sand, sand, and extremely gravelly sand. Clay content ranges from 2 to 5 percent.
Reaction is slightly alkaline or moderately alkaline.
The rock fragment content averages from 30 to 70 percent. Amanda, Crouse, Greybrook, Kendallville , Martinsville, Owosso, Relay, Richardville, Riddles, Sisson, and Skelton soils average less than 30 percent rock fragments in the lower part of the series control section. Belmore, Chenault, Conestoga, Grellton , Hickory, Hollinger, Kanawha, Letort, and Nodine soils average more than 5 percent clay in the lower part of the series control section. Chili soils do not have calcium carbonate in the lower part of the series control section. Coggon soils have redox depletions in the series control section.
