The depth to carbonates commonly is slightly less than sola thickness. The loamy waterlaid sediments are about 30 to 50 inches thick. The sola typically are neutral or mildly alkaline ranging to moderately alkaline in the lower part. Thickness of the mollic epipedon ranges from 10 to 24 inches and may extend into the B horizon. The Bg and 2Bg horizons have dominant hues of 2.5Y or 5Y, values of 4 to 6, and chromas of 2 or less.
Mottles commonly have higher chromas.
Higher chromas in the 2Bg horizons are allowed in the range. The Bg horizons are dominantly clay loam or silty clay loam with a high sand content and may contain up to 5 percent gravel. Thin horizons of loamy sand or textures with up to 50 percent gravel are not excluded. The 2Bg horizons are commonly silty clay loam and range to silty clay or clay. Gravel content is less than 10 percent in the 2Bg4 horizons.
