Reaction ranges from very strongly acid to moderately acid, unless limed. The Bw horizon has hue of 7.5YR through 5Y, value of 4 through 6, and chroma of 3 through 8. It is silt loam or very fine sandy loam. Bw horizons have weak or moderate, granular or subangular blocky structure except some subhorizons can be massive.
