Solum thickness ranges from 20 to 40 inches. Kaolinite is the dominant mineral in the clay fraction with detectable amounts of illite, vermiculite, montmorillonite, chlorite and interstratified clays. Gravel, channery and stone size fragments of quartzite and quartz are present throughout the profile. Rock fragments range from 5 to 40 percent in the horizons of the solum and from 10 to 90 percent in the C horizon. Weighted average of rock fragments is less than 35 percent in the control section.
Reaction ranges from extremely acid to strongly acid throughout.
Where cultivated the Ap has hue of 10YR, chroma of 3 or 4 and value of 2 or 3. Values, when dry, are 6 or higher. Uncultivated A horizons have hue of 10YR to 5YR, value of 2 to 3, and chroma of 0 to 2. Fine earth textures of the A horizons are loam, sandy loam and silt loam. The A horizons are generally channery or gravelly.
