HISTORY: The first record of the Campo was in 1576. A Spanish governor learned of the iron from the Indians who reportedly believed that it had fallen from heaven. The governor sent an expedition under the command of one Captain de Miraval who brought back a few pieces of a huge iron mass he called Meson de Fierro (large table of iron).
The location of the find was the Campo del Cielo (field of the sky or heaven), a fitting name for the location of a meteorite. Since the Indians believed that the irons fell from heaven the name may have come from the meteorites. The area is an open brush-covered plain that has little water and no other rocks--very good country in which to locate meteorites.
The next record of Campo Del Cielo meteorites was about 200 years later in the late 1770s. The Spanish thought some pieces might be silver ore, but once they tried to process it, they found that it was only iron. A Spanish navy lieutenant excavated one specimen which he believed weighed 14 to 18 tons. This may have been the Meson de Fierro. He left he mass in place and it was not seen again--or was it?
In the 1800s more smaller irons were found. A pair of flintlock pistols reportedly made of this material were given to President James Monroe. Later analyses showed that the iron was not meteoritic. In the 1900s. systematic exploration revealed many more large masses; however, the Meson de Fierro remained lost.
In 1992, American meteorite dealer Robert Haag was arrested by Argentine authorities while transporting a 37 ton meteorite from the area. Haag had purchased the mass from a local person who claimed ownership. Unfortunately, the authorities disagreed. Haag was released and the huge meteorite remains in Argentina. Whether this is the famous Meson de Fierro remains for speculation.
