    A1—0 to 10 centimeters (0.0 to 3.9 inches); very dark grayish brown (10YR 3/2), gray (10YR 6/1), dry; sand; weak coarse granular structure; loose, nonsticky, nonplastic; 21.0 very fine roots and 0.5 fine roots; 21.0 very fine interstitial pores; fragments; moderately acid, pH 6.0, hellige-truog; clear wavy boundary. Lab sample # 40A23420; moist when described;
    A2—10 to 61 centimeters (3.9 to 24.0 inches); light gray (10YR 7/2), light gray (10YR 7/2), dry; sand; massive; loose, nonsticky, nonplastic; 0.1 medium roots and 0.5 fine roots; 21.0 very fine interstitial pores; fragments; moderately acid, pH 6.0, hellige-truog; gradual wavy boundary. Lab sample # 40A23421; moist when described;
    B21IR—61 to 91 centimeters (24.0 to 35.8 inches); light gray (10YR 7/2), very pale brown (10YR 7/3), dry; sand; massive; loose, nonsticky, nonplastic; 0.1 fine roots; 21.0 very fine interstitial pores; fragments; very strongly acid, pH 4.5, hellige-truog; gradual smooth boundary. Lab sample # 40A23422; moist when described;. concretions make up from 5 to 15 percent of mass and tend to occur in pockets 1 to 2 feet across, see horizon below for additional detail.
    B21IR—61 to 91 centimeters (24.0 to 35.8 inches); fragments. Lab sample # 40A23423; moist when described;
