Barcelona soils have bedrock between 40 and 60 inches.
Bromer soils have a thicker sola.
The Lauer and Lieber soils have the base of the argillic deeper than 40 inches. Taggart soils havethe base of the argillic deeperthan 40 inches. Tiro soils have a lithologic discontinuity in the subsoil within 40 inches of the soil surface. Niagara soils are nearly level to gently sloping soils of lake plains. Slopes are mainly less than 5 percent in gradient, but they are as much as 15 percent in a few places.
