Permeability is moderate.
Slope ranges from 0 to 60 percent. Mean annual temperature is about 48 degrees F, and mean annual precipitation is about 30 inches. The solum ranges from 42 to more than 60 inches in thickness. Thickness of loess is greater than 80 inches. Depth to carbonates is typically greater than 60 inches.
