The top of '''Devils Tower''' is flat, which is strongly suggestive of having been formed by a flood that submerged it, despite its summit being over 5000 above sea level. The walls are almost perfectly vertical; the top is about the size of a football field. | The top of '''Devils Tower''' is flat, which is strongly suggestive of having been formed by a flood that submerged it, despite its summit being over 5000 above sea level.
