Depth to the C horizon ranges from about 40 to 50 inches in the microknolls to about 50 to 65 inches in the microdepressions. Calcareous material, where present, follows the wavy upper boundary of the C horizon but extends in the AC3 in some microknolls. It is medium acid through mildly alkaline. Moist values are 4 in more than 50 percent of the pedon. Mottles range from few to many and are faint to distinct in shades of gray, brown, olive, and yellow.
Reaction ranges from medium acid to mildly alkaline.
Mottles are few to many faint to distinct shades of gray, brown, olive, or yellow. Reaction ranges from slightly acid to moderately alkaline and a few pedons are calcareous below about 30 inches. The C horizon is light brownish gray, light gray, light olive gray, light yellowish brown, or brownish yellow with many mottles of these same colors and olive yellow and reddish yellow. It is noncalcareous or calcareous shale, shaly clay, or clay that is moderately alkaline and contains a few soft calcium carbonate bodies. There are no competing series in the same family.
