The Allende meteorite fell on February 8, 1969. A fireball appeared in the southwest of the province of Chihuahua in Mexico; its brightness was increasing while people could hear dull detonations. The meteor exploded near the village of Pueblito de Allende, throwing thousands of stones over a surface of approximately 300 square kilometers. The people of the region grabbed numerous meteorites. Five days after the fall, Brian Mason and Roy Clarke Jr, from the Smithsonian Institute, arrived on site, retrieving specimens for scientific research. The strewnfield measuring fifty kilometers long, is one of the longest listed for a meteorite. The main mass weighed around 110 kg.
The meteorite of Allende was the first extraterrestrial rock analyzed because of its freshness by Dr. Elbert A. King in the laboratory of lunar rocks (NASA Lunar Receiving Lab) to be brought back by the Apollo missions from 1969.
