The BC horizon has hue of 7.5YR through 2.5Y, value of 4 or 5, and chroma of 2 through 4. It has texture, structure, and consistence similar to the Bw horizon. The C or 2C horizon has hue of 7.5YR through 2.5Y, value of 4 or 5, and chroma of 2 through 4. Texture of the fine-earth fraction ranges from loamy sand to loam or is stratified sand and gravel. The Farnham series is the only series in the same family.
Farnham soils have rock fragments dominated by shale.
The Alto , Braceville , Chenango , Ellington , Hoosic , Pompton , and Tunkhannock series are similar soils in related families. Alton , Chenango, Hoosic, and Tunkhannock soils lack redoximorphic depletions within a depth of 24 inches. Braceville soils have a fragipan. Castile soils are nearly level to undulating soils on glacial outwash plains, valley trains and associated kames, eskers and water-deposited parts of moraines. Slopes range from 0 to 15 percent.
