description Erg Chech Overview
Erg Chech is an extensive sand sea in the western Sahara, lying mainly in southwestern Algeria and extending toward neighboring Mali and Mauritania. Like other ergs, it consists of broad fields of wind-shaped dunes within a hyper-arid landscape. The region gave its name to Erg Chech 002, an ungrouped achondrite meteorite found in Algeria in 2020 whose ancient crystallization age and unusual chemistry provide evidence about early differentiated bodies in the solar system.
