C IL
Southern IL is sort of undefined.
The first glacier stopped north of Shawnee National Forest. Pretty thin below that, and a bit rolling.
That second glacier stopped at IL Rt 16 (a bit north of I-70). Actually lots of really flat ground south of there, but still clay timber soils, not the black ground.
IL seems to have plenty of rivers and rolling ground around them.
