Color--hue of 10YR to 5Y, value of 2 to 5, and chroma of 1 or 2
Texture--commonly clay loam but ranges to sandy loam, or sandy clay loam: it commonly contains thin lenses of sand and clay
Redoximorphic Features--Few to common masses of iron accumulation in shades of brown, yellow, or red are present in some pedons.

Texture--stratified sandy clay loam to sand that may contain thin layers of clay loam, silty clay, or clay.
