pale brown (10YR 6/3) dry; weak fine granular structure; friable, slightly
hard; about 15 percent rock fragments of till pebbles and channers and
flags of limestone and siltstone; slightly effervescent; slightly alkaline;
abrupt wavy boundary.
AC=3 to 6 inches; mixed yellowish brown (10YR 5/4), light brownish gray
(10YR 6/2), and strong brown (7.5YR 5/6) silt loam; moderate medium platy

C1=6 to 10 inches; brown (10YR 4/3) silty clay loam; strong thick horizontal
layers; massive; firm, hard; about 15 percent rock fragments of till pebbles
and channers and flags of limestone and siltstone; few light brownish
gray (10YR 6/2) soil fragments; few distinct very dark gray (10YR 3/1)
coatings on faces of soil fragments; strong effervescent; slightly alkaline;
abrupt wavy boundary.
C2=10 to 33 inches; mixed brown (7.5YR 4/4) and pale brown (10YR 6/3)
silty clay loam; massive; firm, hard; few vertical cleavage planes; few
gray (10YR 5/1) soil fragments throughout, and few yellowish red (5YR
5/6) soil fragments in the lower part; about 18 percent rock fragments
of till pebbles and channers and flags of limestone and siltstone; strong
effervescent; slightly alkaline; clear smooth boundary.
C3=33 to 45 inches; mixed brown (10YR 4/4) and pale brown (10YR 6/3) silty
clay loam; massive; firm, hard; few gray (10YR 6/1) and grayish brown
(10YR 5/2) soil fragments; about 18 percent rock fragments of till pebbles
and channers and flags of limestone and siltstone; strong effervescent;

Range in Characteristics: The A horizon is silt loam, silty clay
loam, clay loam, or loam; or gravelly, stony, or channery analogs. Typically
it has weak or moderate, fine or medium structure. The C horizon is silty
clay loam, silt loam, loam, silty clay, or clay loam; or the channery,
gravelly, or cobbly analogs. Thin strata or small pockets of coarser or
finer textured material are in some pedons.
Drainage and Permeability: Well drained. Runoff is slow to very
rapid. Permeability is moderately slow.
Use and Vegetation: Many areas that have a stony surface or steep
slopes are seeded to grass-legume mixtures or fescue and are used for
pasture. Other areas have a mixture of boradleaf trees, or pine plantation
and are used for recreation or wildlife habitat. Some areas have been
graded and used for meadow, small grain, or row crops. Corn, milo, soybeans,
and wheat are the principal crops.
