    2Cr—132 to 203 centimeters (52.0 to 79.9 inches); 40 percent light gray (10YR 7/1) interior and 30 percent pale red (10R 6/3) interior and 30 percent yellowish brown (10YR 5/8) interior extremely gravelly sandy clay loam; massive; extremely firm*; 20 percent by volume angular 75-162-250 millimeter unspecified fragments and 40 percent by volume angular 2-39-75 millimeter unspecified fragments; very strongly acid, pH 4.6, hellige-truog. Lab sample # MU050768. All gravels and cobbles are chert. I'm always suspicious of textures in Cr due to ambiguity of material and resistance to dispersion.
