Campo del cielo was a very large meteorite fall, it is theorized to be a large piece that broke up when entering the atmosphere, some 4000 to 6000 years ago. Campo del cielo means field of the sky or heaven, which is a very appropriate name. This meteorite was first discovered in 1576, the meteorite fragments have been found over a large area, both inside and outside of craters. Most Campo pieces come from Argentina, although some very recent finds suggest fragments may be found as far away as Peru. This is one of the few iron meteorites. It has been studied extensively by many Universities and may also be found in several museum collections. This meteorite has a unique crystallization known as the Widmanstatten crystal structure. These lines are shown as a unique etched pattern on the meteorite. This pattern is the result of the meteorite cooling in outer space over billions of years. Although not as finely detailed as other meteorites, these pieces still display this pattern when cut and etched with acid. As this meteorite is composed mostly of iron, care must be taken to prevent the piece from rusting. Direct exposure to water is not recommended. Oil the piece regularly with mineral oil or olive oil. Do not leave the piece laying around on wet surfaces.
