Garwin soils have a lower content of sand in the sola, prismatic structure in the lower B horizons and in the upper C horizons and in addition lack free carbonates above depths of 40 inches. Hartsburg soils have a lower content of sand and lime concretions in the B2 horizon. Wacousta soils have thinner sola. Marcus soils have finer textured A and upper B horizons. Maxcreek, Maxfield and Rushmore soils have a loamy 2C horizon of glacial till beginning within depths of 40 inches.
Ossian soils have thicker sola and free carbonates at a greater depth.
Patton and Pella soils typically have a 10YR hue in the B horizon and loamy till or outwash 2C horizons at depths of about 40 inches. Sable soils contain less sand and have thicker sola. These soils have plane to slightly concave slopes. They are on level to gently undulating lake plains or ground moraines that are mantled with lacustrine sediments. Slope gradient is less than 2 percent.
