I'm pretty flat here, but if I travel a bit North East there are some lateral moraines and terminal moraines. They are most prevalant around what's called the "Holy Hill" area, and the Kettle Moraine area. A 100 or so years ago, some of them were mined for their iron ore. The old mine shafts are still there, and I remember going exploring in them when I lived over in that part of the state.
