The huge solitary sandstone and conglomerate pinnacles that are scattered over the Colorado Plateau are so unusual as to appear nearly impossible. The theory on this particular monument is that there were cracks in the original sandstone that filled with a harder mixture of sandstone blocks and other types of material that resisted erosion more than the surrounding rocks. Whatever the explanation, the reality exceeds belief. It is hard to get a perspective of the size of these huge rocks. Either they appear to be small due to the vastness of their surroundings or very large when you finally get close to one.
