History
During 2007 fall and winter about 100 kilograms (220 lb) of meteorites were collected in the Erg Chech, north of Taoudenni.[2] Desert nomads reported that during daytime in July 2007 several detonations were heard over a wide area, a smoke cloud was seen and several stones fell from the sky, however no fireball was reported. Ouled Bleila was the finder of the first meteorites, but he died in October 2007 in a car accident on his way back from the trip to the Chergach strewn field. According to the Tuareg people, the elliptical strewn field stretches for more than 20 kilometres (12 mi).[2]
