These are the Alvin , Boyer , Burnsville , Council , Dryden , Eleva , Elmdale , Hillsdale , Lamont , Mecan , Oshtemo , Perrin , and Wyocena series in the same family and the Kidder , Locke , Miami , and Spinks series. Alvin, Elmdale, and Hillsdale soils have thicker and more acid sola. Boyer soils have C horizons of stratified gravel and coarse sand. Burnsville, Oshtemo, and Perrin soils have sand and coarse fragments in the solum and C horizons. Council soils have finer textured, more acid C horizons.
Dryden soils have mottles of low chroma in the lower part of the argillic horizon.
Eleva soils have a paralithic contact at depths between 20 and 40 inches. Lamont soils are more acid and are coarser textured in the lower C horizon. Mecan soils have thicker sola. Wyocena soils have less silt and clay in their sola and have loamy sand C horizons. Kidder and Miami soils are fine-loamy.
