...James G. Kirchner Abstract A lacustrine silt layer has been identified within the Radnor Till Member of the Glasford Formation (Illinoian) in three outcrops and six boreholes in central Illinois. Two of three outcrops were sampled for study. The silt is up to 1.5 m thick, light gray in the lower...
