Here's a picture of the rock wall at Stone Mountain Sky Hike. It's not really difficult to climb this wall, not only because of the automatic belaying device, but because the holds are really close together and easy to grab on to. If you look at the pictures of the walls at Stone Summit on the online tour of the gym. you can tell that it will be much more difficult to take on those walls.
