I need hills with beautiful nature that are near Chicago or Milwaukee, in Illinois or Wisconsin. Closer to both major cities is a plus. I also need a mountain-like hill that is solid on the side with a flat surface for experienced rock/mountain climbers. Something like the image below. Doesn't have to be high up, just a vertical drop to the bottom, solid rock. In fact, it's probably better if it's not high up.
Any ideas? I know, it makes more sense to look out west. You don't need to tell me that.
