Some pedons have a thin layer with slight brittleness in the middle or lower part of the Bt horizons. The BC horizon has texture of silt loam or silty clay loam, with strata of fine sandy loam in some pedons. Structure is weak, coarse subangular or angular blocky, or very coarse prismatic, or thin to thick platy. Reaction ranges from very strongly acid to neutral. The C horizon has hue of 10YR or 7.5YR, value of 4 or 5, and chroma of 3 to 6.
Texture is commonly stratified silt, silt loam, or silty clay loam.
Some pedons have strata of loam, fine sandy loam or silty clay, or lenses of very fine sand or fine sand. Reaction ranges from very strongly acid to slightly alkaline. These are the Appleriver , Blair , Bunkum , Fishhook , Freeburg , Geff , Muren , Reesville , Torox , and Xenia series. Appleriver, Muren, Reesville and Xenia soils lack stratification in the series control section. Blair, Fishhook, and Geff soils have a thicker solum.
