Thickness of the A horizon, depth to the layer highest in clay, maximum percent clay, thickness of Bt horizon, depth to carbonates, and thickness of loess over till typically decreases as gradient increases on convex slopes. Both the loess and glacial till have montmorillonite as the dominant clay mineral. The Ap or A horizon has hue of 10YR, value of 2 or 3 and chroma of 1 or 2. Clay content is 19 to 24 percent. Sand content is less than 15 percent.
Reaction ranges from moderately acid to neutral.
The E horizon, when present, has hue of 10YR, value of 4 or 5 and chroma of 2 or 3. Clay content is 19 to 24 percent. Sand content is less than 15 percent. Reaction ranges from moderately acid to neutral. On eroded areas, the E horizon is completely or partly mixed in the Ap horizon.
