Star dunes are pyramidal sand mounds with slipfaces on three or more arms that radiate from the high center of the mound. They tend to accumulate in areas with multidirectional wind regimes.<ref name=dkp/> Star dunes grow upward rather than laterally. They dominate the [[Grand Erg Oriental]] of the Sahara. In other deserts, they occur around the margins of the [[sand sea]]s, particularly near topographic barriers. In the southeast [[Badain Jaran Desert]] of China, the star dunes are up to 500 metres tall and may be the tallest dunes on Earth.
