Campo Del Cielo
The Campo del Cielo refers to a group of iron meteorites found in northwest Argentina. The crater field covers an area of 3 by 18.5 kilometres (1.9 by 11.5 mi) and contains at least 26 craters.
The craters’ age is estimated as 4,000–5,000 years. The craters, containing iron masses, were reported in 1576, but were already well known to the aboriginal inhabitants of the area. The craters and the area around contain numerous fragments of an iron meteorite. The total weight of the pieces so far recovered is about 100 tonnes, making the meteorite possibly the heaviest one ever recovered on Earth.
