Campo del Cielo

Campo del Cielo refers to a group of iron meteorites and the area in Argentina where they were found. The site straddles the provinces of Chaco and Santiago del Estero, located 1,000 kilometers north-northwest of Buenos Aires, Argentina and approximately 500 kilometres southwest of Asunción, Paraguay. The crater field covers 18.5 by 3 kilometres and contains at least 26 craters, the largest being 115 by 91 metres.

The craters are estimated to be four to five thousand years old. They were reported to the general public in 1576, but were already well-known by aboriginal peoples. The craters and surrounding areas contain many fragments of an iron meteorite. In total, approximately 100 tonnes of fragments have been recovered, the most of any meteorite finding.
