    Ap—0 to 18 centimeters (0.0 to 7.1 inches); 95 percent dark reddish brown (2.5YR 3/4) broken face sandy clay loam; 28 percent clay; 5 percent dusky red (2.5YR 3/2) fine and medium faint irregular mottles; weak very coarse subangular blocky structure; friable, slightly sticky, nonplastic; moderate permeability; low excavation difficulty; 3.0 very fine and fine roots throughout; 3.0 medium tubular and 4.0 fine tubular and 0.5 coarse tubular pores; 50 percent faint dark reddish brown (2.5YR 3/4), moist, clay films on all faces of peds; fragments; abrupt smooth boundary.; moist when described; observed in pit, large or quarry. Field describers noted that the quartz grain reflect light.
