On the general geological map of Iowa there are three peculiarities in the areal distribution of the geological formations represented which excite particular attention. They indicate that not only has the terranal story not been yet all told but that owing to unusual misinterpretation the real facts have been unwittingly greatly distorted. One of these features is the notable southeastward straight trend of the eastern border of the basal Missourian, or Bethany, limestone as it leaves our state in Wayne County - a direction nearly at right angles to that which we would ordinarily expect.
