Riddles soils have lamellae in the lower part of the argillic horizon. Wawaka soils formed in loess and till overlying outwash.

GEOGRAPHIC SETTING: The Crouse soils are on side slopes and foot slopes on terminal moraines. Slope ranges from 6 to 50 percent. The soils formed in a thin layer of loess and recent Wisconsinan till over older Wisconsinan till mixed with Illinoian till. Mean annual precipitation ranges from 838 to 1016 mm (33 to 40 inches). Mean annual air temperature ranges from 11 to 13 degrees C (51 to 55 degrees F).

GEOGRAPHICALLY ASSOCIATED SOILS: These are Miamian, Russell and Xenia soils. The well drained Miamian soils are moderately deep to dense till and are on ridge tops and similar positions. The well drained Russell and moderately well drained Xenia soils have thicker loess mantles and are on ridge tops.

DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY: Well drained. The depth to the top of an intermittent perched high water table ranges from 107 to 122 cm (3.5 to 4 feet) between January and May in normal years. The potential for surface runoff is medium to very high. Saturated hydraulic conductivity is moderately high. Permeability is moderate.

USE AND VEGETATION: Crouse soils are cultivated or pastured. Some areas are wooded. Corn and soybeans are the principal crops.

DISTRIBUTION AND EXTENT: Southwestern Ohio; MLRA 111D. The series is of small extent.
