Primary structure is moderate or strong prismatic, and consistence is firm or very firm, and brittle. Reaction ranges from strongly acid to neutral. The 2Bx horizon has hue of 5YR through 5Y, value of 4 or 5, and chroma of 2 through 4, with few or common redoximorphic features. Texture of the fine-earth fraction is silt loam or loam, and contains 10 to 27 percent clay. Primary structure is moderate or strong prismatic, and consistence is firm or very firm, and brittle.
Reaction ranges from strongly acid to neutral.
The 2C horizon has the same range in color and texture as the Bx horizon except some pedons are sandy loam below 40 inches. The horizon is massive and may have has plate-like divisions. Consistence is firm or very firm. Reaction ranges from moderately acid to moderately alkaline. The Amboy and Williamson series are in the same family.
