The sculpturing of these rock masses is the result of the combined action of rock jointing, and chemical and physical (mechanical) weathering. The combination of these processes results in spheroidal weathering, the peeling-off of thin concentric shells of rock that form spherical rock masses. Spheroidal weathering results from slight pressures feldspar.
