Despite the evidence suggesting a meteor impact, Meteor Crater lacked a smoking gun—or in this case, a smoking hot chunk of meteorite. Barringer himself had funded several drilling operations on the floor of the crater. He was certain that the meteor that struck the Earth must have been ten million tons. He dug downwards, hoping to find the massive object that caused the crater. Unfortunately, the mine shaft had to be abandoned when it hit the water table and turned to quicksand (Yikes!). Desperate to find something, the team consulted astronomer F. R. Moulton, who broke the bad news: Given the size of the crater, and the energy at which it struck, the object Barringer was looking for was likely only 300,000 tons in mass, and it had probably vaporized on impact. Visitors to the crater can still see the abandoned mine shaft at the bottom of the crater.
