The mean annual soil temperature at 20 inches is 55 to 59 degrees F. The A or Ap horizon has color value of 3 to 6 and chroma of 2 to 4. Where the value of the A or Ap horizon is 3 and chroma is 3 or less moist, dry value is 6 or more. Reaction is strongly acid to slightly acid. The E or BE horizon, where present, has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 3 to 6. It is silt loam.
Reaction is strongly acid to neutral.
The Bt horizon has hue of 5YR to 10YR, value of 3 to 5 and chroma of 3 to 8. Chroma is as low as 2 in the layer immediately above the 2Bt horizon. Texture is silty clay loam or silty clay or their gravelly or very gravelly analogues. It has from 0 to 35 percent gravel and 0 to 10 percent cobbles. Reaction is strongly acid to moderately alkaline.
