Joints may run both horizontally and vertically through a sheet of granite. Because of this, stacked layers of giant boulders, sitting one on top of the other, can be produced by weathering. In some cases, extreme rounding occurs on the under surfaces of a rock, leaving intact only a small balancing point where it rests upon the boulder beneath. Balancing rocks eventually become unstable and roll off, or they might stay in place but disintegrate into smaller boulders. Rarely, a large boulder will tip over to form an arch across other boulders. Examples of balancing rocks can be found all over Girraween, but the best known examples are Granite Arch, The Sphinx and, of course, Balancing Rock on top of The Pyramid.
