These are mainly the Mendota and Plano soils and, in some places, the LeRoy soils. They are in areas next to the Markesan series where the loess or silt mantle is thicker over the till. Both Mendota and Plano have thicker sola and are fine-silty. In nearby areas where the surface layer is lighter colored, the LeRoy soils are associates. Surface runoff is medium.
Permeability is moderate.
