Over 360 million years ago, an asteroid or cornet struck this area at more than 10 miles/second forming a crater 2.5 miles across and, in seconds, ejecting 0.3 cubic mile of rock. Deformed limestone beds seen in adjacent cliffs were violently uplifted to form a shattered central peak. This crater, now buried beneath younger rocks, was used by NASAlUSGS in training Apollo astronauts and represents an important class of craters found on other planets and satellites in our solar system.
