About 4,000 to 5,000 years ago, a huge chunk of space rock fell in Argentina, but it didn't fell in one piece. It broke up as it entered the earth's atmosphere creating a meteorite shower with pieces ranging from a few grams to several tons.
Most of the larger fragments fell over a narrow belt of land an area now known as the Campo del Cielo meteorite field. The impact left at least twenty-six craters. Some meteorite fragments punched deep holes into the earth, as in the case of a 14-ton meteorite.
