Mottles of high and low chroma are present. The upper part of the Bw horizon ranges from slightly acid to strongly acid while the lower part ranges from neutral to medium acid. A BC horizon is in some pedons. The C horizon has hue of 7.5YR or 10YR, value of 4 or 5, and chroma of 1 through 6. It is loamy sand, coarse sand, or sand.
Reaction ranges from neutral to medium acid.
These are the Corunna , Darfur , Dassel , Gilford , Hanska , Jubilee , and Lyles soils in the same family and the Ambraw , Gannett , Granby , and Shaffton series. Corunna soils have loamy or silty calcareous 2C horizons above 40 inches. Darfur soils are higher in fine and very fine sand, are shallower to carbonates, and lack hues of 7.5YR or redder. Dassel soils have distinct textural stratification in the Bw horizons and are shallower to free carbonates. Gilford soils have free carbonates in the 2C horizon and are in areas receiving greater rainfall.
