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 ina 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]
