These walls are located in the waterfall glen forest preserve. It does not get much sun so it stays wet for a long time after a rain. The best looking wall is right next to the water fall and is solid rock, which is pretty neat. the others have more moss/lichen on them. So far every time I have visited this location it was too wet to climb, hence why there are no problems set yet. I am thinking that they will be better in the fall. If you go and are able to climb it be sure to add the problem to this page. Also should mention its a bit of a highball.

The best way to get to this spot is to drive to these coordinates (41.690246, -88.000947) and park on the side of the road in the gravel before the gate. Do not go past the gate with your car. There is a trail that leads around the gate which gets you into the preserve. Once you're past the gate there is another trail between the railroad tracks and the gate that will lead you to the creek's cascades, turn left on the trail and head down stream until you see the wall/waterfall
