Mean annual temperature ranges from about 50 to 54 degrees F, and mean annual precipitation ranges from 32 to 36 inches. These are the competing Douds and Lindley soils and the Gara soils. Gara or Lindley soils commonly are upslope on that portion of the glacial till slope that was dissected in late Wisconsinan time. Gara soils contain less clay in the Bt horizons. Somewhat poorly drained.
Permeability is slow.
Depth to an intermittent perched water table is 1 to 3 feet at some time from November through July in most years. A few areas are used for cultivated crops. Native vegetation was deciduous trees. These soils are of moderate extent. About 10,000-12,000 acres are in Iowa.
