Hartsburg, Madelia, Pella, Rushmore, and Wacousta soils typically have thinner sola and free carbonates at depths between 12 and 40 inches. Mascoutah soils contain less than 7 percent sand in the lower part of the series control section. Maxfield soils formed in loess less than 40 inches thick and in loam till. Ossian soils formed in silty alluvium. Patton soils have sola between 24 and 42 inches thick and C horizons of stratified silt loam and silty clay loam lacustrine sediments.
Elpaso soils are on nearly level to level areas of Wisconsin till plains and moraines.
Slope gradients range from 0 to 2 percent. The soils formed in 40 to 60 inches of loess and the underlying calcareous glacial till. These are the Andres , Chenoa , Dana , Elliott , Flanagan , Graymont , Lisbon , Raub , Saybrook , Symerton , and Varna soils. The somewhat poorly drained Andres and the well and moderately well drained Symerton soils formed in loamy outwash and in the underlying silty clay loam glacial till. The somewhat poorly drained Chenoa and moderately well drained Graymont soils formed in 20 to 40 inches of loess and the underlying silty clay loam glacial till.
