    Oi—0 to 3 centimeters (0.0 to 1.2 inches); slightly decomposed plant material; fragments.
    A—3 to 13 centimeters (1.2 to 5.1 inches); very dark grayish brown (10YR 3/2) rubbed, brown (10YR 5/3) rubbed, dry; loam; moderate fine granular structure; very friable; 10.0 very fine to medium roots; 1 percent by volume 600-?-? millimeter unspecified fragments and 2 percent by volume 250-425-600 millimeter unspecified fragments and 3 percent by volume 75-162-250 millimeter unspecified fragments and 5 percent by volume 2-39-75 millimeter unspecified fragments; very strongly acid, pH 4.8, hellige-truog; abrupt wavy boundary. Lab sample # MU048225
    2Bt1—13 to 39 centimeters (5.1 to 15.4 inches); yellowish red (5YR 4/6) clay; strong fine subangular blocky structure; firm; 0.5 medium and coarse roots and 3.0 fine roots; 75 percent prominent reddish brown (5YR 4/4) clay films; fragments; strongly acid, pH 5.2, hellige-truog; clear wavy boundary. Lab sample # MU048226
    2Bt2—39 to 59 centimeters (15.4 to 23.2 inches); 75 percent yellowish red (5YR 4/6) and 25 percent strong brown (7.5YR 5/6) clay; moderate fine subangular blocky structure; firm; 0.5 medium roots and 3.0 fine roots; 75 percent prominent dark red (2.5YR 3/6) clay films; fragments; very strongly acid, pH 4.9, hellige-truog; gradual wavy boundary. Lab sample # MU048227
    2Bt3—59 to 82 centimeters (23.2 to 32.3 inches); strong brown (7.5YR 5/8) clay loam; 1 percent brown (10YR 5/3) fine distinct mottles; moderate fine subangular blocky structure; firm; 3.0 very fine and fine roots; 15 percent prominent dark red (2.5YR 3/6) clay films and 15 percent prominent dark yellowish brown (10YR 4/4) clay films and 35 percent prominent yellowish red (5YR 4/6) clay films; 1 percent black (10YR 2/1) iron-manganese masses and 1 percent fine iron-manganese concretions; fragments; very strongly acid, pH 4.8, hellige-truog; clear wavy boundary. Lab sample # MU048228. A few pockets of heavier clay texture were observed.
    2Bt4—82 to 105 centimeters (32.3 to 41.3 inches); reddish yellow (7.5YR 7/8) and strong brown (7.5YR 5/8) clay loam; 10 percent dark red (2.5YR 3/6) medium prominent mottles; weak medium prismatic parts to moderate fine and medium subangular blocky structure; firm; 0.1 very fine and fine roots; 15 percent prominent brown (10YR 5/3) clay films on vertical faces of peds; 1 percent fine black (10YR 2/1) iron-manganese concretions and 1 percent black (10YR 2/1) iron-manganese masses and 10 percent fine reddish brown (5YR 4/4) masses of oxidized iron; fragments; very strongly acid, pH 4.7, hellige-truog; gradual wavy boundary. Lab sample # MU048229. A few pockets of finer clay were observed.
    2Bt5—105 to 140 centimeters (41.3 to 55.1 inches); reddish yellow (7.5YR 7/8) and strong brown (7.5YR 5/8) clay loam; moderate thick platy parts to moderate fine subangular blocky structure; firm; 0.5 fine roots; 4 percent prominent dark red (2.5YR 3/6) clay films on vertical faces of peds; fragments; very strongly acid, pH 4.8, hellige-truog; clear smooth boundary. Lab sample # MU048230. The boundary dips towards the steeper backslope. Over a one meter horizontal distance the boundary depth varies from 47 to 57 inches. A ten inch dip back and below the higher slope gives a slump profile postulated by mass movement with rotation.
    2BC—140 to 173 centimeters (55.1 to 68.1 inches); 75 percent strong brown (7.5YR 5/8) and 25 percent strong brown (7.5YR 5/6) coarse sandy loam; weak very fine subangular blocky structure; friable; 0.1 very fine roots; 3 percent yellowish brown (10YR 5/4) clay films on vertical faces of peds; 30 percent medium and coarse black (10YR 2/1) masses of dark accumulation; fragments; strongly acid, pH 5.5, hellige-truog; clear wavy boundary. Lab sample # MU048231. At 67 inches the horizon slopes with the depth ranging from 59 to 76 inches over a three foot distance. The boundary still dips toward the higher landscape; discontinuity below.
    2C1—173 to 206 centimeters (68.1 to 81.1 inches); 70 percent strong brown (7.5YR 5/8) and 30 percent reddish yellow (7.5YR 7/8) coarse sandy loam; massive; friable; 0.1 very fine roots; 4 percent yellowish brown (10YR 5/4) clay films on vertical faces of peds; 30 percent medium and coarse black (10YR 2/1) masses of dark accumulation; 15 percent fine lime masses; fragments; neutral, pH 7.1, hellige-truog; clear smooth boundary. Lab sample # MU048232. The horizon boundary was more level at this depth.
    2C2—206 to 216 centimeters (81.1 to 85.0 inches); 55 percent strong brown (7.5YR 5/8) and 45 percent light yellowish brown (10YR 6/4) fine sandy loam; massive; friable; 3.0 roots; faint silt coats on horizontal faces of peds; 15 percent fine black (10YR 2/1) iron-manganese masses; 35 percent fine lime masses; fragments; slightly alkaline, pH 7.5, hellige-truog. Lab sample # MU048233. The term laminar was used to describe thin layers related to a different material. These concentrations may, or may not, relate to sedimentary bodies. A black sample from each layer between Bt4 and 2C2 horizons were tested with H2O2, and only a sample from the 2C2 layer reacted.
