More info:

The Campo del Cielo refers to a group of iron meteorites or to the area where they were found. This area is situated on the border between the provinces of Chaco and Santiago del Estero, 1,000 kilometers (620 mi) northwest of Buenos Aires, Argentina. The crater field covers an area of 3 by 18.5 kilometers (1.9 by 11.5 mi) and contains at least 26 craters, the largest being 115 by 91 metres (377 by 299 ft).

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.

The largest two fragments, the 30.8-ton Gancedo and 28.8-ton El Chaco, are among the heaviest single-piece meteorite masses recovered on Earth, along with the 60-ton Hoba and a 31-ton fragment of the Cape York meteorite.
