Three kinds of column-like formation are discussed. There are columns of unconsolidated material, often differing from their surroundings, embedded in sand or drift. There are pillars of consolidated material, often sandstone, embedded in rock. And there are free-standing solid pillars. It is proposed that all of these kinds of pillars, and also potholes, are to be ascribed to one cause: disintegration following upon the release of pressure as the material was raised out of the water at the end of the Noachian Flood. It is hard to believe that sedimentary processes could have caused these formations; hence the cross stratification, often found with them, can not be an effect of sedimentation. Some reasons are suggested why the study of these formations may be especially worth while to a Creationist.
