Wow, look at the size of that bowl. Looking into Meteor Crater, Winslow, Arizona I have a difficult time envisioning a 160-foot wide nickel-iron meteorite crashing to earth at 26,000 mile an hour.
However, the collision happened around 50,000 years ago, resulting in a crater 1 mile across, 2.4 miles in circumference and more than 700 feet deep. The meteor’s impact, released energy greater than 20-million tons of TNT, and shook the southwestern plain for miles. The meteor left little evidence of its origin behind, it vaporized on impact with the earth. Moreover, erosion has done little to alter the original crater.
Furthermore, during the 1960’s NASA used the crater to provide extensive scientific training for the Apollo astronauts, on their way to the moon. Subsequently, Dr. Eugene Shoemaker, Ed Chow, and Don Milton, all of the U.S. Geological Survey, discovered new minerals coesite and stishovite at the crater.
After looking at the enormous hole in the ground, I can understand why the massive crater remains one of the best-preserved meteor impact sites, in the United States.
