The BE or EB horizon, where present, has value of 4 to 6, and chroma of 1 or 2. Reaction is strongly acid to neutral. Redoximorphic iron depletions and concentrations have hue of 7.5YR, 10YR, or 2.5Y, value of 2 to 6 and chroma of 1 to 6. Texture is silty clay loam, silt loam, or clay loam. Clay content averages 20 to 35 percent in the upper part and averages 20 to 30 percent in the lower part.
Reaction is strongly acid to slightly acid.
