The only terrain you are going to find within that 60 mile radius is going to be in a quarry unless you are OK with bluffs instead of rock face cliffs. The lakeshore north of Milwaukee has 200' bluffs and gorges for quite a ways and it is peppered with parks. If not, you are limited to a quarry. Everything in this part of the country was scraped flat by the glaciers except for the area around Devil's Lake which was, for some reason, avoided by the advancing ice. That area is called "The Driftless Zone" and is actually quite exotic in terms of geography.
