The largest intact asteroid impact crater in the U.S. lies completely buried under the verdant cornfields of north-central Iowa, near a town called MANSON. The crater is about 23 miles in diameter, making it about 30 TIMES larger than Meteor Crater, in Arizona.

Some scientists believe that the impact produced a tidal wave, or Tsunami, in the shallow Cretaceous Sea that covered much of the area at the time. They theorize that such a tsunami deposited a very special layer of sediment called Crow Creek, which can be found today exposed in isolated patches in South Dakota. The Crow Creek sediment has been proven to contain the tell-tale shocked quartz and feldspar fragments blasted from the Manson asteroid impact. Because the crater itself is completely buried and there is none of the impact rock available at the surface,the Crow Creek fragments are the ONLY AVAILABLE remnant of this Earth-shaking event.
