San Pedro Jacuaro 19°46'N, 100°39'W Estado de Michoacan de Ocampo, Mexico Fall: 1 December 1968 Ordinary chondrite (LL6) History: In December 1968, Jose Dimas Bautista of San Luis Potosi, Mexico, heard a loud "airplane type" sound while working outside the mines in the Sierra Madres mountains near San Pedro Jacuaro. A search recovered a 460 g mass from a fresh hole in the sand. He kept it in his possession until July 2003, when he brought it to the attention of Robert Cucchiara of Alameda, California, who recognised it as a meteorite. Source (PDF)
