This paper is primarily a defense of my claim that Iraq is divided by an ancient curved escarpment stretching between Hit and Samarra. This geological formation is shown to be a relict shoreline where the post-Flood waters rested after the earth dried up. The Griffith and White challenge to this does not hold up; they mistakenly claim that the close-by and far more recent Tharthar depression in Iraq is what I am referring to. There are implications for the location of the Tower of Babel in this disagreement; those who erroneously believe that the Tower was built in south Iraq do not understand that the entire area below the escarpment was under water when the Tower was built. The southern half of Iraq is a delta that was formed by sediments from the Ice Age meltdown, and all structures built on it are post Ice Age. Therefore Babel and Babylon are not to be confused; the former was built in Northern Mesopotamia and the latter was located in southern Iraq, south of the Hit–Samarra escarpment.
