Lines analogous to isohyets were drawn with respect to molar ratios of CaO, K2O, and Fe2O3 to ZrO2. The resulting maps demonstrate the close relationship of loess thickness to intensity of soil development and identify a north-south band of soils in southern Illinois that are the most intensely weathered soils in the state. The youngest or least developed soils identified by the lines occur in thick loess deposits of extreme northwestern Illinois. Isoweathering lines cannot be drawn in the area of Wisconsin drift because of the penecontemporaneity of loess on the drift and many local sources within the drift sheet area.
