Acapulco fell in El Quemado Colony, just outside Acapulco, Mexico, August 11th of 1976.
According to the Meteoritical Bulletin (MB 55), the finder’s account is that “the bolide followed a west to east trajectory, producing a buzz similar to that of a small aeroplane and an impact like that of a cannon ball. It landed by 11 in the morning, and it was collected from a small crater, some 30 cm deep, 15 minutes later; the bush around was splashed radially away and the stone was cool.”
Acapulco is an achondrite, and the namesake for the Acapulcoite meteorite group; primitive achondrites that have undergone only partial melting.
