They formed in residuum weathered from metasedimentary rocks such as phyllite, slate, and metsandstone. Slope ranges from 7 to 95 percent. Sylco channery silt loam forested. Depth to slate, metasandstone, or phyllite bedrock that is not fractured enough to contain some fine material ranges from 20 to 40 inches. The average content of these fragments between 10 inches and bedrock ranges from 35 to 50 percent.
Fragments are channers, flagstones, or stones.
The amount of weatherable minerals, mainly chlorite, sericite, and hydrobiotite, exceeds 30 percent in the silt and sand fractions. The soil is strongly acid to extremely acid. Transition horizons have colors and textures similar to adjacent horizons. The A1 horizon has hue of 10YR, value of 3 or 4, and chroma of 2 to 4. The A2 horizon has hue of 10YR, value of 4 or 5, and chroma of 3 or 4.
